Use backfill free from stones large enough to interfere with compaction; large or frozen lumps that will not break down readily under compaction; and wood or other extraneous material. Obtain backfill material from excavatian or from other sources. Place backfill in layers na greater than 10 in. deep (loose measurement) in areas not support�ng a completed roadbed, retaining wall, or embankment. Place backfiill in uniform layers no greater than 8 in, deep (loose measurement) in areas suppo�ing a portian oi a roadbed, retaining wall, or embankment. Compact each layer to meet the density requirements of the roadbed, retaining wall, embankment material, or as shown on the plans. � , �, r Bring each layer of backfill material to the moisture content needed ta obtain the required density. Use mechanical tamps or rammers to compact the backfill. Rollers may be used to compact backfill if feasible. Cohesionless materials may be used for backfilling. Use cohesionless materials that conform to the requirements of Table 1. Table 1 Cohesionless Material ��ad��+�n Li�ti� e_.......�._...._............_ ize � Percent 3' 0 _a� �....m.A..� ........... ..._._..... #10 See Note' �zoo _..........�. _ _ so-�oo 1 N�.1� sieve r�q���r���r�ts are [i to 30% reiained when used as aggregale cement-stabilized backfill. Compact cohesionless materials using vibratory equipment, water-ponding, or a combination of both. 3.3.2, ridge Foundations, Retaining Walls, Manholesllnlets, and Box Culverts, Place backfill against the structure only after the concrete has reached the design strength required in Item 421, "Hydraulic Cement Concrete." Backfill retaining walls with material meeting the requirements of Item 423, '°Retaining Walls." Backfill around bridge foundations, manholesrnlets and culverts using material with particles no more than 4 in. in greatest dimension and a gradation that permits thorough compaction. Use rock or gravel mixed with soil if the percentage of fines is enough to fill all voids and ensure a uniform and lhoroughly compacted mass of proper density. Use mechanical tamps and rammers to avoid damage (o the structure where backfill materiaf is being placed too close to the structure to permit compaction with blading and rolling equipment. Avoid wedging action of back611 against structures. Step or serrate slopes bounding the excavation to prevent such action. Place backfill uniformly around bridge foundations. Place backfill equally and in uniform layers along both sides of manholes/inlets and culverts. The Engineer may require backfilling of structures excavated into hard, erosion-resistant material, and subject to erosive forces, with stone or lean concrete. Box culverts may be opened to traffic as soon as enough backfill and embankment has been placed over the top to protect culve�s against damage from heavy construction equipment. Repair damage to culve� caused by construction traffic at no atlditional expense to the Department. 3.3,3. Pipe. Bring backfill material to the proper moisture condition after installing bedding and pipe as required and place it equally along both sides of the pipe in uniform layers no greater than 8 in. deep (loose measurement}. Compact each lift mechanically. Thoroughly compact materials placed under the haunches of the pipe to prevent damage or displacement of the pipe, Place backfill in this manner to the top-of-pipe elevation. Place and compact backfill above the top of the pipe in accordance with Section 400.3,3.1., "GeneraB." The Engineer may reject backfill material containing more than 20% by weight of material retained on a 3 in. sieve with large Bumps not easiBy broken down or that cannot be spread in loose layers. MateriaB excavated by a trenching machine will generally meet the requirements of this Section as long as large stones are not present. Place and compact addiGonal material where pipe extends beyond the toe of slope of the embankment and the depth of cover provided by backfill to the original ground level is less than the minimum required by the specifications for the type of pipe involved until the minimum cover has been provided. ��; A • . 1 ': ,,1 • . . _ _ '. . •. •. �.: r 1�.:..# -r / �.��♦ • • . .1 "�:1 1. , �1: ! ��... � . � . ��.:. .1��.'�.

Additional measurements or calculations will be made if adjustments of quantities are required. 4.1, Structural cavation. Unless shown on the plans as a pay item, structural excavation quantities shown are for information purposes only. When structural excavation is specified as a pay item, structural excavation for pipe headwalls, inlets, manholes, culve� or storm drain exlensions less than 15 ft. long, bridge abutments, retaining walls, and side road and private entrance pipe cufverls will not be measured. No allowance will be made for variance from plans quantity incurred by an alternate bid. When specified as a pay item, structural excavation will be measured by the cubic yard as computed by the average end areas method. Excavation diagrams on the plans take precedence over the provisions of this Article. 4.1,1. Boundaries of easurement. 4.1.1.1. Pipe. 4.1.1.1.1. Pipe up to 42 Inches. For pipe up l0 42 in. nominal or equivalent diameter, no material outside of vertical planes 1 ft. beyond and parallel to the horizontal projection of the outside surfaces of the pipe will be included. 4.1.1.1.2. Pipe Larger than 42 Inches. For pipes larger than 42 in. nominal or equivalent diameter, no material outside of ve�ical planes located 2 ft. beyond and parallel to the horizontal projection of the outside surfaces of the pipe will be included. Quantities for excavation in fill above naturaf ground include 1 ft. above the top of the pipe regardless of the height of completed fill. Excavation for pipe will be measured between the extreme ends of the completed structure including end appurtenances as shown on the plans and from centerline to cente�ine of inlets, manholes, etc. 4.1,1.2, Structural Plate Structures. No material outside of vertical planes 3 ft, beyond and paralfel to the horizontal projection of the outside surfaces of the structure will be included. When the quafity of the existing soil or embankment is less than that of the proposed backfill matenal, the limits of ineasurement will be extended to vertical planes located 1/2 of the span beyand the horizontal projection of the outside surfaces of the structure. , .. � . : � • , . • - . . � + - . � � - . - . � . - � • � � . . r. . - � - •�t. � . ;�. � . . 1- . �- ,•� - - * ' � . � - �. r' * , ��r used. When plans provide the option of cast-in-place or precast boxes, measurement will be based on the cast-in-place option. Where excavation in addition to that allowed for the footings is required for other po�ions of the structure, measurement for the additional excavation will be limited IateraBly by vertical planes 1 ft. beyond the face of the member and parallel to it, and veRically to a depth of 1 ft, below the bottom of the member. 4.1.1.4. Excavation near Roadways and Channels. At structure sites other than culverts and pipe excavations, the measurement of structural excavaGon arill include only material below or outside the limits of the completed road or channel excavation. Roadway and channel excavation will be paid under Item 110, "Excavation," For culve�s except side road and private entrance culve�s, excavation within the limits of the structure and below or outside the limits of the completed roadway excavation will be measured as structural excavation. 4.1.2. Falsework. No measurement will be made for excavation necessary for placing forms or falsework that exceeds the limits given in Section 400.4.1.1., "Boundanes of Measurement." 4.1.3. Swelling.

Do not excavate a shaft within 2 shaft diameters (clearj of an open shaft excavation, or one in which concrete has been placed in the preceding 24 hr. Dispose of material excavated from shafts and not incorporated into the finished project in accardance with �he plans and with federal, state, and local laws. Provide suitable access, lighting, and equipment for proper inspection of the completed excavation and checking the dimensions and alignment of shafts excavation. 3.2. Core Holes. Take cores to determine the character of the suppo�ing materials if directed. Use a method that will result in recovery of an intact sample adequate forjudging the character of the founding material. Such cores should be at least 5 ft, deeper than the proposed founding grade or a depth equal to the diameter of the shaft, whichever is greater. Take these cares when the excavation is complete. 3,3. Casing. Use casing when necessary to prevent caving of the material, to exclude ground water, when slurry is used for hole stabilization, or when required as part of the Contractor°s Safery Plan. Provide casing with an outsitle diameter not less than the specified diameter of the shaft. The portion of shaft below the casing may be as much as 2 in. smaller than the specified shaft diameter. No extra compensation will be made for concrete required to fill an oversized casing or oversized excavation. Use casing strong enough to withstand handfing stresses and pressures of concrete and of the surrounding earth or water, and that is wate�tight, smooth, clean, and free of accumulations of hardened concrete. - � � . �� ' . � . , . . � � �-� . �- . ,��-� � �- , ! �.• � .�� � - ,� , ,. .� . � �� � � . - � • �- . � � ► .� . �� . -, ,� �� �-. � • Leave casing in place only if authorized or shown on the plans, Extract casing only after pfacing the concrete to an appropriate level. Maintain sufficient cancrete in the casing at all times to counteract soil and water pressure. Rotate or move the casing up or down a few inches if necessary before and during concrete placement to facilitate extraction af the casing. 3.4. Requirements for Slurry Displacement ethod. When soil conditions warrant, use the slurry displacement method to construct drilled shafts unless otherwise shown on the plans, Use this methad to support the sides of the excavation with processed mineral slurry that is then displaced by concrete to form a continuous concrete shaft. . i. - , � �. � 1 �-� • ��� � �-r- �� � R� a . . * � ,_ . . , . � �s � , . -', � r; �- . 1 � .�� � , !� * r �. �' � - . _ . . �,; . # � . .�. � •' ;. . � . � � .,! . �; • � [ �-� . �.. + � . ..��. �1 1,'. ^ � .

Maintain a head of slurry in the shaft excavation at or near ground level or higher, as necessary, to counteract ground water pressure during and after drilling. � Use an air lift or proper size cleanout bucket, just before placing reinforcing steel, to remove any material that may have fallen from the sides of the excavation or accumulated on the bottom after the completion of drilling. Use a cleanout bucket if material is too large to be picked up with an air lift. Re-process the hole with the auger as directed if concrete placement is not started �thin 4 hr. of the completion oi the shaft excavation. Then clean the bottom with an air lift or cleanout bucket, and check the slurry at the bottom of the hole far compliance with the sBurry requirements of Article 416.2., "Materials." Agitate the congealed slurry to liquefaction if the sBurry forms a gel before concrete placement, and whenever directed, Recover and dispose of all sluRy as approved, and in accordance with all federal, state, and local laws. Do not discharge slurry into or in close proximity to streams ar other bodies of water. 3.5. Reinforcing Steel, Completely assemble the cage of reinforcing steel, and place it as a unit immediately before concrete placement. The cage consists af longitudinal bars and lateral reinforcement (spiral reinforcement, lateral ties, or horizontal bands). Connect individual segments with couplers or by lapping steel as appraved if overhead obstacles prevent placement of the cage as a single unit. Extend the reinforcing steel cage as follows if the shafl is lengthened beyond plan length unless directed other�se. Extend the cage to the bottom for shafts supporting structures other than bridges. Extend the cage to 25 ft. or to the bottom, whichever is sho�ter, for bndge shafts with plan fengths less than 25 ft. Do not extend the cage far bridge shafls with plan lengths at feast 25 ft. that are lengthened less than 33% of plan length. Extend the cage as directed for bndge shafts with plan lengths at least 25 ft. that are lengthened more than 33% of plan length. If the cage does not reach the bottom of the shaft, it may be suspended, or a po�tion of the longitudinal steel may be extended to support the cage on the bottom of lhe shaft. Bars used to extend or suppo� the cage may be lap spliced or welded by a qualified welder. Place lhe extension at the bottom of the shaft. Tie spiral reinforcement to the longitudinal bars at a spacing no more than 24 in., or as required for a stable cage. Ensure lateral reinforcement is not welded to longitudinal bars unless otherwise shawn on the plans, Center the reinforcing steel cage in the excavation using approved "ralle�' type centering devices unless othenMse approved, Use concrete or plastic chairs to keep the reinforcing cage off of the bottom of the hole. Use centering devices starting at 1.5 ft. off from the bottom of the cage and spaced ve�ically at intervals not exceeding 10 ft. Use a minimum of 3 centering devices per level at a spacing not to exceed 30 in. Flat or crescent-shaped centralizers ("sleds'� are not allowed. Support or hold down the cage to control vertical displacement during concrete plecement or extraction of the casing. Use support that is concentric with the cage to prevent racking and distortion of the steel. Check the elevation of the top of the steel cage before and after concrete placement or after casing extraction when casing is used, Downward movement of the steeB up to 6 in. per 20 feet of shaft length and upward movement of the steel up to 6 in. total are acceptable. Maintain the minimum length of steel required for lap wilh column steel. Use tlowel bars if the proper lap length is provided both into the shaft and into the column. Locate and tie all tlowel bars into the cage before placing concrete or insert dowel bars into fresh, workable concrete. Locate and tie anchor bolts when required before placement of concrete. Use templates or other devices to assure accurate placement o( anchor bolts, � � , , .: --. . �• . ��. - . ,;� � -- � - •�,�- , .. � . • - • �> . - . �� •� ., - � • . �� . , � . . � �- - � , . �- � . - �- -, - �- •� � � • � �� �� - �, •- �. - Table 4 aximum Concrete Placin� T�m��rat�ur� Mix Design r- . �� . �F�����3i� Form portions af drilled shaft that project above natural ground. . �� , -# -. r. - �. � � � �= � � . � . �; - . �- � . - ., . �- . •. ._ - . --. �� . �� �-. - . - , .. , �--. � - . � ._ �.�•+ •. �� :�... / . !

Protect concrete placed under weather conditions where weather may adversely affect results. Permission given by the Engineer for placing during cold weather does not relieve ihe Contractor of responsibility for producing concrete equal in quality to that placed under normal conditions. Remove and replace concrete as directed at the Contractor's expense if it is determined unsatisfactory due to poor conditions. Do not place concrete in contact with any maierial coated with frost or with a temperature of 32°F or lower, Do not place concrete when the ambient temperature in the shade is below 40°F and falling unless approved. Place concrete when the ambient temperature in the shade is at least 35°F and rising or above 40°F, Provide and install recording thermometers, maturity meters, or other suitable temperature measuring devices to verify all concrete is effectively protected as follows: Maintain the temperature at all surfaces of concrete in bents, piers, culverf walls, retaining walls, parapets, wingwalls, top slabs of non-direct traffic culverts, and other similar formed concrete at or above 40°F for 72 hr, from the time of placement. Maintain the temperature of afl other cancrete, including the bottom slabs (footings) of culverts, placed on or in the ground above 32°F for 72 hr. from the time of placement. m Lf� .�� �. �- � -�. �, .� �,'- �• � � . � .�, � � � � +- -� � r , c � � - = . , � �- ., , ., . , � � . - ,-- _ -, _ -. - , .. .. � . - . .- . •., � -�•.-�- , *. .� .�-� ►, - . . .- � . •. - . � . � .• -�� �- --. . . �-. -�.- + . � -� � - . ,-. �- - � � . - - . �- -� _ , , � � • . , - �� , - � - . � .R- .,, .�. . � � . . . . � � „- • � � - .�� � -� - �� . - , _ . � � . . �- - � �-.� � � � . • � . � _�� � _ � � �-�. � -.� ��-- . .- - ,. � �� - �.- - � �• � �-�� -+ r� � � . � . � - � . � . � . . • - - � - _ _ ;- • � � � � • . � - .�� . -, - �, . � .. . . . � -- �� - .-�� � .- �.-� --� - � _- .---� ��.- - Support the tremie or operate the pump so it can be easily moved harizontally to cover afl the work area and ve�ically to control the concrete flow.

Keep forms for mass placements in place for 4 days following concrete placement unless other�se approved based on the outcome of the heat control plan outlined in Section 420.4.7.14., "Mass Placements.°' Leave in place weight-supporting forms and falsework spanning more than 1 ft. for alf bridge components and culvert slabs except as directed otherwise until the concrete has attained a compressive strength oF 2,500 psi. Remove forms for other structural components as necessary. Remove inside forms (walls and top slabs) for box culverts and sewers after concrete has attained a compressive strength of 1,600 psi if an approved overhead support system is used to transfer the weight of the top slab to the wells of the box culvert or sewer before removal of the support provided by the forms. Forms or parts of forms may be removed only if constructed to permit removal r�thout disturbing forms or falsework required to be left in place for a longer period on other po�ions of the structure. Remove all metal appliances used inside forms for alignment to a depth of at least 1l2 in. from the concrete surface. Make the appliances so metal may be removed without undue chipping or spalling of the concrete, and so it leaves a smooth opening in the concrete surface when removed. Do not bum off rods, bolts, or ties. Remove all forms and falsework unless otherwise directed. 4.12. Defective ork. Repair defective work as soon as possible. Remove and replace at the expense of the Contractar any defect that cannot be repaired to the satisfacGon of the Engineer. 4,13. Ordinary Surface Finish.

A new ce�ification or signed and sealed report is required every time a plant is moved. Plants with a licensed professional engineer's inspection require re-inspection every 2 yr. Provide a copy of the certification or the :ID signed and sealed inspection report to the Engineer. Remove equipment or facilities from service until corrected when they fail to meet speciFication requirements. When allowed on ihe plans or by the Engineer, for concrete classes not identified as structural concrete in Table B or for Class C concrete not used for bridge-class structures, the Engineer may inspect and approve alf plants and trucks instead of the NRMCA or non-Department engineer-sealed certifications. The criteria and frequency of Engineer approval of plants and t�ucks is the same used for NRMCA certificatian. Inspect and fumish inspection reports on the condiGon of blades and fins and their percent �ar from the original manufacturer's design for truck mixers and agitators annually. Repair mixing equipment exhibiting 10% ar more wear before use. If an inspection within 12 mo. is not practical, a 2-mo. grace period (for a maximum of 14 mo. between inspections) is permitted. 3.1.1. Scales. Check all scales before beginning of operations, after each move, or whenever their accuracy or adequacy is questioned, and al least once every 6 mo. Immediately correct deficiencies, and recalibrate. Provide a record of calibration showing scales in compliance with ASTM C94 requirements. Check batching accuracy of volumetric water batching devices at least every 90 days. Check batching accuracy of chemical admixture dispensing detices at least every 6 mo, Perform daily checks as necessary to ensure measuring accuracy, 3.1.2. Volumetric ixers. Pravide volumetric mixers with rating plates defining lhe capacity and the perforrnance of the mixer in accordance with the Valumetric Mixer Manufacturers Bureau or equivalent. Provide volumetric mixers that comply with ASTM C685. Provide test data showing mixers meet the uniformity test requirements of Tex-472-A.

Submit previous sa6sfactory field data, data from a new trial batch, or other evidence showing the change will nat adversely affect the refevant properties of the concrete when changes are made ta the rype, brand, or source of aggregates, cement, SCM, water, or chemical admixtures. Submit the data for approval before making changes ko the mix design. A change in vendor does not necessarily constitute a change in materials or source, The Engineer may waive new trial batches when there is a prior record of satisfactory performance with the ingredients. During concrete production, dosage changes of chemical admixtures ussd in the irial batches will not require a re-evaluation of the mix design. � � � � The Contractar has the option of performing trial batches in conjunction with concrete placements except for SCC mixtures, when new trial batches are required during the course of the project. If the concrete fails to meet any requirement, the Engineer will detertnine acceptability and payment adjustments. Establish the strength—maturity relationship in accordance �th Tex-026-A when the maturity method is specified ar permitted. When using the maturity method, any changes in any of the ingredients, including changes in proportions, will require the development of a new strength—maturity relationship for the mix. ix Design of Record. Once a trial batch or previously saGsfactory field data substantiates the mix design, the proportions and mixing methods used become the mix design of record. Do not exceed mix design water- to-cement ratio. Production Testing. 4.4.1. Aggregate Moisture Testing. Determine moisture content per Tex-409-A or Tex-425-A for coarse, intermediate, and fine aggregates at least twice a week, when there is an apparent change, or for new shipments of aggregate, When aggregate hoppers or storage bins ere equipped with properly maintained electronic moisture probes for continuous moisture determination, moisture tests per Tex-409-A or Tex-425-A are not required. Eleckronic moisture probes, however, must be verified at least every 90 days against Tex-409-A and be accurate to within 1,0% of the actual moisture cantent, When producing SCC, and when aggregate hoppers or storage bins are not equipped �th electric moisture probes, deternrine the moisture content of the aggregates before producing the first concrete batch each tlay. Thereafter, determine the moisture content every 4 hr. or when there is an apparent change while SCC is being produced. 4,4.2. Aggregate Gradation Testing. Perform a sieve analysis in accordance with Tex-401-A on each stockpile used in the blend at least one day before producing OAG concrete when producing optimized aggregate gradation concrete. Perform sieve analysis on each stockpile after every 16,000 cubic yards of OAG concrete producetl. Provide sieve analysis data to the Engineer. 4.5. easurement of aterials, 4.5.1.

Make construclion joinls square and normal to the forms unless otherwise required. Use bulkheads in the forms for all ve�ical joints. Thorough(y clean the hardenetl concrete surface of all loose material, faitance, dirt, and foreign matter, and saturate it �th water. Remove all free water and moisten the surface before concrete or bonding grout is placed against it. Ensure the surface of the existing concrete is in a saturated surface-dry (SSD} condition just before placing subsequent concrete. Prewet the existing concrete by ponding water on the surface for 24 hr, before placing subsequent concrete. Use high-pressure water blasting ta achieve SSD conditions 15 to 30 min. before placing the concrete if ponding is not possible. An SSD condition is achieved when the surface remains damp when exposed to sunlight for 15 min, Draw forms tight against the existing concrete to avoid mortar loss and offsets at joints. Bonding agents are not required unless indicated othenNise. Coat the joint surface with bonding mortar, grout, epoxy, or other material as indicated on the plans or other Items if a bonding agent is required. Provide Type V epoxy per DMS-6100, "Epoxies and Adhesives," for bonding fresh concrete to hardened concrete.

Avoid cold joints in a monolithic placement. Sequence successive layers or adjacent portions of concrete so they can be vibrated into a homogeneous mass with the previously placed concrete before it sets. 4.6.9, Consolidation. CarefuBly consolidate concrete and flush mortar to the form surfaces with immersion type vibratars. Do not use vibrators that operate by attachment to forms or reinforcement except where approved on steel forms. Vibrate the concrete immediately after deposit. Systematically space points of vibration to ensure complete consolidation and thorough worfcing of the concrete around the reinforcement, embedded fixtures, and into the comers and angles of the forms. Insert the vibrator vertically where possible except for slabs where it may be inserted in a sloping or horizontal posi6on. Vibrate the entire depth of each lift, allowing the vibrator to penetrate several inches into the preceding lift. Do not use the vibrator to move the concrete to other locations in the forms. Do not drag the vibrator through the concrete. Thoroughly consolidate concrete along construc6on joints by aperating the vibrator along and close to but not against the joint surface. Continue the vibration un61 the concr�te surrounding reinforcements and fixtures is completely consolidated. Hand-spade or rod the concrete if necessary to ensure Oushing of mortar to the surface of all forms. Concentrate vibration efforts along the beams lines when precast concrete panels are used for deck construction. 4.6.10. Installation of Dowels and Anchor Bolts. Install dawels and anchor bolts by casting them in-place or by grouling with grout, epoxy, or epoxy mo�ar unless noted otherwise. Form or drill holes for grouting. Use only epoxy when installing horizontal dowels into the edges of slabs. Follouv the manufacturer's recommended installation procedures for pre-packaged grout or epoxy anchor systems. Test anchors if required on the plans or by other Items. Drill holes for anchor bolts to accommodate the bolt embedment required by the plans. Make holes for dowels at least 12 in. deep unless otherwise shawn on the plans. Make the hole diameter at least twice the dowel or bolt diameter, but the hole need not exceed the dowel or bolt diameter plus 1-112 in. when using cementitious grout or epoxy mortar. Make the hole diameter 1116 to 114 in. greater than the dowel or bolt diameter when using neat epoxy unless indicated otherwise by the epoxy manufacturer. Thoroughly cbean holes of all loase material, oiB, grease, or other bond-breaking substance, and blow them clean with filtered compressed air. Use a v�re brush followed by oil-free compressed air ta remove afl loose material from the holes, repeating as necessary until no more material is removed. Ensure holes are in a surface-dry condition when epoxy type materials are used and in a surface-moist condition when cementi6ous grout is used. Develop and demonstrate for approvel a procedure for cleaning and preparing the holes for installation of the dowels and anchor bolts. Completely fill the void between the hole and dowel or bolt with grouting material. Follow exactly the requirements for cleaning outlined in the product specifications for pre-packaged systems, Pravide a Type III epoxy per DMS-6100, "Epoxies and Adhesives," when neat epoxy is used for anchor bolts or dow�ls. Provide Type VIII epoxy per DMS-6100, "Epoxies and Adhesives," when an epoxy grout is used. Provide grout, epoxy, or epoxy mortar as the binding agent unless otherwise indicated on the plans. Provide other anchor systems as required on the plans. 4.6.11, Placing Concrete in Cold Weather. Protect concrete placed under weather conditions where weather may adversely affect results. Permission given by the Engineer for placing during cold weather does not relieve the Contractor of responsibility for producing concrete equal in quality to that placed under normal conditions. If concrete placed under poor canditions is unsatisfactory, remove and replace it as directed at Contractor s expense. ;;, � Do not place concrete in contact �th any material coated with frost or with a temperature of 32°F or lower. Do not plece concrete when the ambient temperature in the shade is below 40°F antl falling unless approved. Place concrete when the ambient temperature in the shade is at least 35°F and rising or above 40°F. Provide and install recording thermometers, maturity meters, or other suitable temperature measuring devices to verify all concrete is effectively protected. Maintain the temperature of the top surface of bridge slabs and top slabs of direct traffic culve�s at 50°F or above for 72 hr. from the time of placement and above 40°F for an additional 72 hr. Use additional covering, insulated forms, or other means and, if necessary, supplement the covering with artificial heating. Avoid applying heat directly to concrete surfaces. Cure as speci6ed in Section 422.4.8., "Final Curing," during this period until all requirements for curing have been satisfied. Have on hand all necessary heating and covering material, ready for use, before permission is granted to begin placement when impending weather conditions indicate the possibBe need for temperature protection. Distress caused by concrete drying out as a result of delayed set and strength gain associated with cold weather are a result of the Contractor's actions and are subject to repair in accordance �th Section 422,4.10„ "Defective Work." 4.6.12. Placing Concrete in Hot eather. Use an approved Type B or D set retarding agent in all cancrete far supe�structures and top slabs of direct traffic cufverts, except concrete containing GGBF slag, when the temperature of the air is above 65°F unless otherwise directed. Keep the concrete at or below the maximum temperature at time of placement as specified above. Sprinkle and shade aggregate stockpiles or use ice, liquid nitrogen systems, or other approved methods as necessary to control the concrete temperature. 4.6.13. Placing Concrete in Superstructure. Place simpfe span bridge slabs without transverse conslrucGon joints by using either a self-propelled transverse finishing machine or a mechanical longitudinal screed unless otherwise shown on the plans. Use of manually operated screeding equipment may be permitted for small placements or for unusual conditions such as narrow widening, variable cross slopes, or transitions. Support the screed adequately on a header or rail system stable enough to withstand the longitudinal or lateral thrust of the equipment. Adjust the profile grade line as necessary to account for variations in beam camber and other factors to obtain the required slab thickness and concrete cover over the slab reinforcement. Set beams and veriiy their surface elevations in a sufficient number af spans so that when adjustment is necessary, the profile grade fine can be adjusted over suitable increments to produce a smooth riding su�iace. Take dead load deflection into account in setting the grades of headers and rail systems. Use construction joints, when required or permilted for slab placements on steel or prestressed concrete beams, as shown on the plans. Release falsework under the spans before placing concrete on steel girder or truss spans, and swing the spans free on their permanent supports. Provide additional camber to offset the initial and final de8ections of the span as indicated on the plans for concrete flat slab, concrete slab, and girder spans cast-in-place on falsewo�k. Provide camber of approximately 318 in. for 30-ft. spans and 1l2 in. for 40-ft. spans to offset initial and final deflections for concrete slab and girder spans using pan forms unless otherwise directed. Provide a camber of 118 in. for 10-ft. spans but no more than 1/2 in. for concrete flat slab, concrete slab, and girder spans not using pan forms when dead load deflection is not shown on the plans. Provide a camber of 114 in. in addi6on to deflection for slabs without vertical curvature on steel or prestressed concrete beams. Provide camber for specified vertical curvature and transverse slopes. Make 1 or more passes with the screed over the bridge slab segment before placing concrete on it to ensure proper operation and maintenance of grades and clearances. Use an approved system of checking to detect any vertical movement of the forms or ialsework. Maintain farms for the bottom surface of concrete slabs, girders, and overhangs to the required vertical alignment during concrete placing. � L� Level, strike off, and screed the surface while carrying a slight excess of concrete ahead of the screed tn fill all low spots as soon as the concrete has been placed and vibrated in a section w+de enaugh to permit working. Move longitudinal screeds across the concrete with a saw-like motion while their ends rest on headers or templates set true to the roadway grade or on the adjacent finished slab. Move transverse screeds longitudinally approximately 1!5 of the drum length for each complete out-and-back pass of the carriage. Screed the surface of the concrete enough times and at intervals to produce a uniform surface true to grade and free of voids. Fog unformed surfaces of slab concrete in bridge slabs and in top slabs of direct tra�c culverts from the time of initial strikeoff of the concrete until finishing is completed and required interim curing is in place. Do nol use iogging as a means to add finishing water and do not work moisture from the fog spray into the fresh concrete. Retard the concrete for simple spans only iF necessary to complete finishing operations or as required by ihis 5ection. Bring the top of curb and sidewalk section to the correct camber and alignment when filling curb forms, and finish them as described in this Item. 4.6.13.1, Transverse Screeding. Install rails for transverse finishing machines that are supported from the beams or girders so the supports may be removed without damage to the slab. Prevent bonding between removable suppo�ts and the concrete in an acceptable manner. Do not allow rail support parts that remain embedded in the slab to project above the upper mat of reinforcing steel. Rail or screed supports attached to I-beams or girders are subject to the requirements of this Item. Pface concrete at a minimum rate of 30 ft, af bridge slab per hour for transverse screeding unless otherwise shown on the plans. Deposit concrete parallel to the skew af the bridge so all girders are loaded uniformly along their length. Deposit slab concrete be en the exterior beam and adjacent beam before placing concrete in the overhang po�tion of the slab. Fumish personnel and equipment capable of placing, finishing, and curing the slab at an acceptable rate to ensure compliance with the specifications. Place concrete in transverse strips. Stert placement at the lowest end on profile grades greater than 1-112%. At the Contractor's option, attach a pan drag and either a carpet or bu�ap drag to the screed assembly to float and provide surface micro-texture in one operation. Adjust the contact pressure of the pan drag to smooth high spots and fill any depressions left by the screed. Adjust the weight or position of the carpet or burlap drag to produce a smooth sandy micro-texture without blemishes, marks, or scratches deeper than 1116 in. Fill screed rail support holes and holes from the Engineer's depth checks for slab thickness and reinforcing cover with concrete, and fiinish them to match the rest of the slab. 4.6.13.2. Longitudinal Screeding. Use of temporary intermediate headers will be permitted for placements over 50 ft. long if the raie of placement is rapid enough to prevent a cold joint and if these headers are designed for easy removal to perrnit satisfactory consolidation and finish of the concrete at their locations unless otherwise shown on the plans. Deposit slab concrete between the exterior beam and the adjacent beam before placing concrete in the overhang portion of the slab. Place concrete in longitudina! strips starting at a paint in the center of the segment adjacenl to 1 side except as this Section indicates, and complete the strip by placing uniformly in both directians toward the ends, Start placing at the lowest end for spans on a profile grade of 1-112% or more. Use strips wide enough that the concrete within each strip remains plastic until placement of the adjecent strip. Place the concrete in proper sequence to be monolithic with the adjacent langitudinal strips of the slabs where monolithic curb construction is specified. 4.6.13.3. Placements on Continuous Steel Units. Place slabs on continuous steel units in a single, continuous operation without transverse construction joints using a self-propelled transverse finishing machine or a mechanical longitudinal screed unless otherv�se shown on the plans, Retard the initial set of the concrete sufficiently to ensure concrete remains plastic in at least 3 spans immediatefy preceding the slab being placed. Use construction joints, when required for slab placements on steel beams or girders, as shown on the plans. Ensure the previously placed concrete aKains a compressive strength of 3,000 psi when staged placement nf a slab is required on the plans before placing the next stage concrete, Multiple stages may be placed in a single day if approved. Use an approved placing sequence that will not overstress any of the supporting members where plans permit staged placing without specifying a particular order of placement. ,;� � 4.6.13.4. Slab and Girder Units. Place girders, slab, curbs of slab, and girder spans monolithically unless otherwise shown on ihe plans. Fill concrete girder stems first, and place the slab concrete within the time limits specified in this Item. Place concrete in the stems for a short distance if using a transve�se screed, and then place the concrete in transverse strips. Fill the outside girder stem first, beginning at the low end or side, if using a longitutlinal screed, and continue placement in longitudinal strips. 4.7. Finish and Interim Curing of Bridge Slabs. Obtain approval of the proposed interim curing methods, equipment, and materials at the pre-pour meeting before placing concrete, Take into accaunt forecast weather conditions to determine the interim curing methods to use. Use work bridges or other suitable facilities to perform all inishing operations and to provide access, if necessary, for the Engineer to check measurements for slab thickness and reinforcement cover. Work the screeded surface to a smooth finish with a long-handled wood or metal float or hand-float it from work bridges over the slab. Floating may not be necessary if the pan float attached to a transverse screed produces an acceptable finish, Avaid overworking the surface of the concrete. Avoid use of finish water. Perform sufficient checks, �tnessed by the Engineer, with a long-handled 10-ft. straightedge on the plastic concrete to ensure the final surface t�ll be within specified lolerances. Make the check with the straightedge parallel to the centeriine. Lap each pass half over lhe preceding pass. Remove all high spots, and fill and float all depressions over 1116 in. deep with fresh concrete. Continue checking and floating unti! the surface is true to grade and free of depressions, high spois, voids, or rough spots. Fill screed-rail support holes with concrete, and finish them to match the top of the slab. Provide a uniform micro-texture using a carpet drag, buriap drag, or broom finish. Finish the surface to a smooth sandy texture without blemishes, marks, or scratches deeper than 1116 in. Apply the surface texturing using a work bridge or platform immediately after completing the straightedge checks. Draw the carpet or burlap drag longitudinally along the concrete surface, adjusting the surface contact area or pressure to provide a satisfactory coarsely textured surface. A broom finish may be performed using a fine bristle broom transversely. For bridge approach slabs the carpet drag, bu�ap drag, or broom finish may be applied either longitudinally or transversely. Evaporation protection is required if the evaporatinn rate exceeds 0.10 Ibslsflhr based on the Evaporation Calculation for ConcrePe Worksheet as sho� on the Department's website, the evaporation rate nomograph in the Portland Cement Association's Design and Control of Concrete Mixfures or if indicated on the plans. 4.7.1. Evaporation Protection. Use one of the following methods for evaporation protection. 4.7.1.1, Evaporation Retardant. Coat ihe concrete surface immediately after the carpet or buriap drag, or broom finish with a single application of evaporatian retardant at a rate recommended by the manufacturer. Do not allow more than 10 min. to elapse belween the texturing at any location and application of evaporation retardant. The evaporation retardant may be applied using the same work bridge used for surface texturing. Do not work the concrete surface once the evaporation retardant has been appfied. 4.7.1.2. et Burlap. Place pre-wet burBap no more than 10 ft. behind the finishing operation. A work bridge may be required to avoid mamng the surface. Ensure the wet bu�ap covers the entire surface. Use sprayers, hoses, sprinklers, or other similar methods to keep the burlap conGnuously wetted un61 application of the final curing. 4.7,2. Interim Curing. Apply int�rim curing using one of the following options after applying the evaporation protection (if needed): 4.7.2.1, embrane Cure. Apply membrane interim curing at a rate of approximately 180 sq. �. per gallon. Apply before the water sheen disappears but do not place over stantling waler. Fog as necessary ta maintain the wet sheen. Do not spray membrane curing on a dry surface. 4.7.2.2. Wet Burlap. Place pre-wet burlap no more than 10 ft. behind the finishing operation. Burlap used for evaporation protection wilf also be considered as the interim curing. ::' � . . . � �� . .�� . _ . _ � ��. -� , - �� •� . . . � , - . , - � - �� -- .�-�-�< . � .- :�-� .- �� . - � ��. , � ..•.. . � �.� - -,, . � . - ��� . �. .: . �� �-. - - . � �.,.. . ,. , . . - .�-� . � - � •. �. � - � �- �� . • � - - . � . ..,... � R �... 1. ,... . � / ..

Do not use seawater or water that stains or leaves an unsightly residue. 4.8.1. Cotton ats. Keep the concrete continuously wet by maintaining wet cotton mats in direct contact �th the concrete for the required curing time. Weight the mats adequately to provide continuous contact with all concrete. Cover surfaces that cannot be cured by direct contact with mats, forming an enclosure well anchored to the forms or ground so outside air cannot enter the enclosure. Provide sufficient moisture inside the enclosure to keep all surfaces of the concrete wet. Use of soaker hoses and plastic covering is acceptable provided the concrele surface remains continuously wet for the required curing duration. � � : .� . - � .� •� . - � . . . �� •� � . . -� ; � � - •. . � � �-- � --, �. -• � � - .�R. .- �. � -� �� • �, . �. �• -�. ,; .� -� - � - �. � . . .� . -, . .� . , - � . • � � ,- �� • - .� . � -. �� . , . �- ,• - 4.9.

Da not bum off rods, bolts, or ties. Remove a!I forms and falsework unless othe�se directed. Apply an ordinary surface 6nish as the finaf finish to the bottom of bridge slabs be en girders or beams, and vertical and boltom surfaces of interior concrete beams or girders unless otherr�se noted. Form marks and chamfer edges do nat need to be smoothed for the bottom of bridge slabs between girders or beams. Remave all fins, runs, drips, or mortar from surfaces that will be exposed. 4,10. Defective ork, The Contractor is responsible for the ride quality of the finished bridge slab. The Engineer will use a 10 ft. straightedge (118 in. in 10 ft,) to verify ride quality and deterrnine Bocalions where corrections are needed. Submit a plan for approval to produce a ride of acceptable quality if the Engineer determines the ride quality is unacceptable. Make all corrections for ride before saw-cutting grooves. Repair defective work as soon as possible. Remove and replace at the expense of the Contractor any defect that cannot be repaired to the satisfaction of lhe Engineer. The Engineer will inspect the deck or slab for plastic shrinkage and settlement cracking after completion of final curing and within 5 days after curing mats are removed, Seal any noted shrinkage cracks attributable to Contractor placing, curing, and 6nishing practices using gravity feed crack repair as directed in accordance with Item 760, "Concrete Crack Repair," at no cost to the Department. Transverse cracks over interior bents in continuous slab units do not need to be sealed in this manner. 4.11. Final SurFace Texture. Saw-cut grooves in the hardened concrete of bridge slabs, bridge approach slabs, and direct tra�c culve�ts to produce the final texturing a�er completion of the required curing period unless otherwise noted. Cut grooves perpendicular to the structure centerline. Cut grooves across the slab within 18 in. of the barrier rail, curb, or median divider. Adjust groove cutting at skewed metal expansion joints in bridge slabs by using narrow-width cutting heads so all grooves end within 6 in. of the joint, measured perpendicular to the centerline of the metal joint. Leave no ungrooved surface wider than 6 in. adjacent to either side of the joint. Ensure the minimum distance to the first groove, measured perpendicular to the edge of the concrete joint or from the junction between the concrete and the metal leg of the joint, is 1 in. Cut grooves continuously across construction joints or other joinis in the concrete less than 1/2 in. wide. Apply tfie same procedure described above where barrier rails, curbs, or median dividers are not parallel to the structure centerline to maintain the 18 in. maximum dimension from the end of the grooves to the gutter line. Cut grooves continuously across formed concrete joints, Provide either a carpet drag or broom finish for micro-texture when saw-cut grooves are not required on the plans. In this case ensure an adequate and consistent micro-texture is achieved by applying enough weight to the carpet and keeping the carpet or broom from getting plugged with grout. For surfaces that do not have adequate texture, the Engineer may require corrective action including diamond grinding or shot blasting. Give a carpet drag, burlap drag, or broom finish to all concrete surfaces to be overlaid when the pBans call for a concrete ove�ay (CO) to be placed on the slab (new construction}. Saw-grooving is not required in this case. Provide an average texture depth for the finish of approximately 0.035 in, with no individual test falling beBow 0.020 in., unfess othervvise shown on the plans, when tested in accordance with Tex-436-A, Revise finishing procedures to produce the desired texture if the texture tlepth falls below whaf is intended. Give all concrete surfaces to be covered a lightly textured broom or carpet drag finish when the plans require an asphalt seal, with or without overlay, on the slab (new construction). Provide an average texture depth of approximately 0.025 in. when tested in accordance with Tex-436-A. � � 5. EASU E E T Reinforced concrete slabs or decks on girders, beams, slab beams, double-T beams, or box beams placed under this Item will be measured by the square foot of slab surface area using the nominal dimensions and configuration shown on the plans. Transverse measurement will be made from outer edge of slab to outer edge of slab (including raised median and sidewalk sections). Longitudinal measurement v�ll be made betw�en ends of units or spans. Diaphragms, haunch concrete, reinforcement, and optional steel diaphragms will be considered as a portion of the slab unless otherwise sho�. An estimated quantity for the haunch between the slab and beams will be included for the Contractor°s information only. No measurement will be made during construction for variation in the amount of haunch concrete due to variations in camber of the beams. Approach slabs and cast-in-place superstructure elements including flat slabs, slab and girder units (pan forrned), and shear keys will be measured by the cubic yard. For slab and girder spans using pan foRns, a quantiry �BI be included for the screed setting required to pravide proper camber in the roadway surface after iomn removal. This is a plans quantity measurement Item. The quantity to be paid is the quantity shoHm in the proposal unless modified by Article 9.2., "Plans Quanbty Measurement.° Addi6onal measurements or calculations will be made if adjustment of quantities is required. The quantities of concrete and reinforcing stee0 shown on the plans are based an a conventionally formed slab. These quantities include amounts for cancrete diaphragms, brackets and other required attachments, and haunch concrete when required, based on the profile grade, theoreticaf camber, and dead load deflection of the beams. No additional measurement will be made for concrete ar reinforcing steel due to a variation in camber of the beams from theoretical camber, or for additional quantities required by optional methods of forming. Additional concrete that may be required by an adjustment af the profile grade line during construction, to ensure proper slab thickness, will not be measured for payment. �.�.�.���,�,_.�.�. - .�..........�. __ _._..._�. � .... 6.

The inspector's acceptance of material or finished members �II not prohibit subsequent rejection if the material or members are faund to be damaged or defective. Replace rejected material promptly. 3.1.9. aterial Identification, Assembly-mark individual pieces and issue cutting instructions to the shop using a system that will maintain identity of the original piece. Idenlify structural steel by standard and grade of steel. Also differentiate between material toughness requirements (CVN, fracture-critical) as well as any other special physical requirements. In addition, identify structural steel for primary members by mill identification numbers (heat numbers). Use an approved identification system. Use either paint or law-stress stencils to make identification markings on the metal. Mark the materiaf as soon as it enters the shop and carry the markings on all pieces through final fabrication, Transfer the markings before cutting steel for pnmary members of bridge structures into smaller pieces. Loss af identification marking on any piece, with no other positive identificetion, or loss of heat number identification on any primary member piece will render the piece unacceptable for use. Unidentifiable material may be approved for use after testing to establish acceptability to the satisfaction of the Engineer. Have an approved tesGng facility perform testing and a licensed professional engineer sign and seal the resufts. 3.2, elding. 3.2.1. Details. 3.2.1.1. Rolled Edges.

Use the bolting crew that will perform the actual work for the calibration and calibrate the wrench in the presence of the Engineer. Follow the bolt-tensioning procedures in Section 447.4.5.3., "Tension Bofts." 4,1.3, Direct-Tension Indicator. Use a ca{ibrated tension-measuring device for compression-type indicators to verify the gap is not less than 0.015 in. or the job inspection gap specified by the manufacturer when tension in the bolt reaches 1.05 times the tension specified in Table 2. Followthe manufacturer°s instructions for pre-installation verification testing methods and frequency for altemative washer-type indicating devices deemed acceptable. . 4,2. Workmanship. The Engineer will disqualify any crewmembers not atlhering to proper installation methods during production work. Disqualified crew may not perform further bolting work uniil they camplete an additional pre-installation verification test suitable to the Engineer. 4.3. General. Ensure all material within the grip of the bolt is steel. Do not allow any compressible material such as gaskets or insulation within the grip. Ensure the sBope of parts in contact with the bolt head or nut does not exceed 1:20 with respect to a plane normal to the bolt axis. Prepare all joint surfaces, including those in contact with the boft heads, nuts, or washers, so that the surfaces are free of dirt, loose rust, loose mill scale, burrs, and other matter that would prevent solid seating of the pa�ts. Replace any bolts and nuts installed for shipping purposes unless the shop drawings indicate the shop- installed bolts are to be fully tensioned in the shop, Da not tension bolts that have been installed snug-tight in the shop. Remove any bolts installed snug-tight in the shop and replace them with new bolts. Inspect and prepare the joint surfaces after removing shop-installed bolts that are not fully tensioned in the shop. Provide a hardened washer for heavy-hex and tension-control bolts under either the nut or the bolt head, whichever is tumed during tensioning. Install hardened washers under both the nut and bolt head of ASTM A490 bolts when the outer plies being fastened have a yield strength less than 40 ksi. Bnstall an ASTM F436 washer for direct tension indicators as follows: under the nut when the nut is tumed and the direct tension indicator is located under the bolt head; between the nut and the direct tension indicator when the nul is turned and the direct tension indicator is located under the nut; under the bolt head when the bolt head is turned and the direct tension indicator is located under the nut; and between the bolt head and the direct tension indicator when the bolt head is turned and the direct iension indicator is located under the bolt head. Tension all bolts to provide the minimum bolt tension values given in Table 2. Erect steel in conformance with Item 441, "SteeB Structures.°° Do not tack-weld any parts to eliminate fitup bolts or to hold parts together while bolting. Remove lubricant from bolt assemblies on painted stnictures after tensioning and before coating the connections. Re-tighten the nuts or tack weld the nuts to the bolts when bolts are used to temporarily support welded diaphragms after completing the welding operations if the diaphragms are over vehicular or pedestrian traffic. ,�� C:F . :, � �, ., - ------ __....��__m.,..��_. � � �. _..

Preparation of Faying Surfaces. Perfomi blast cleaning or painting of faying surfaces in accordance with Item 441, "Steel Structures." Provide an SSPC-SP 10 blast cleaning before shipment for weathering steel. Do not wire-brush weathering steel faying surfaces. Roughen galvanized iaying surfaces by hand wire-brushing. Do not use power wire brushes to roughen galvanized faying surfaces. 4.5. Bolt Installation, Use the following procedure for bolt installation of a complete connection: 4,5.1. Fair-Up Holes. Use a minimum number of erection or drift pins, as directed, in the holes to "fair-up" all holes. 4.5.2, Install Bolts. Install bolts in all remaining holes of the connection. Do not use excessive torce, which results in damage to the threads, to install the bolts. 6ncrease the number of erection or drift pins as necessary to align the holes if force is required to install the bolts. Do not ream the holes unless approved. Ream the holes in accordance with Section 441.3.11,5., "Misfits," if approved. Remove the erection or drift pins and install bofts in these holes. Bring the connection to a full snug-tight condition by snugging systematically from the most rigid part of the connectian to the free edges. The snug-tight condition is deflned as the tightness that exists when the plies of the joint are in firm, full contact and all of the bolts in the joint have been tightened sufficiently to prevent lhe removal of the nuts without the use of a wrench. A snug-tight condition can usually be attained by a few impacts of an impact wrench or the full effort of a worker using an ordinary spud wrench as demonstrated in ihe installation verification test. As necessary, re-snug previously snugged bolts that may have relaxed as a result of the subsequent snugging of adjacent bolts to ensure all bolts are simultaneously snug-tight and the connection plates are in full contact. Fully tighten a minimum number of bolts as directed until the plies are in full contact if snugging tloes not bring the plies of the joint into full contact. Ma�C these bolts as fitup bolts. Use a non-galvanized ASTM A325 bolt of the same diameter as a fitup bolt in connections requiring the use of galvanized ASTM A325 bolts. Re-snug all remaining bolls. Do not use washer-rype indicating devices to bring the connection to a snug-tight condition. Rather, install heavy-hex bolt assemblies in a sufficient number of holes (approximately 20%) to attain firm, full contact between plies. Remove the heavy-hex bolts and install the washer-type indicating device assemblies after firm contact is established by connections in surrounding bolt holes. 4.5,3, Tension Bolts. Loosen all fitup bolts after tensioning all the other bolts in the connection. Ungalvanized ASTM A325 bolts used as fitup bolts may be reused in a connecUon using this type of bolt, Replace all galvanized bolts and ASTM A490 balts used as fitup bolts. Tension these remaining untensioned bolts in accordance with this paragraph. Ensure the element not tumed by the wrench {bolt head or nut) does not rotate. 4.5.3.1, 7urn-of-the-Nut ethod, Match-mark the nuts and the protruding bolt ends atter the bolts have been brought up to snug-tight condition and before fina6 tensioning so that actual rotation can be determined. � . , . .� • � - �, � . , - R � -, . . �. , .- -� ,�- . . - . . , - - .; � � � � �.

Completely weld a jaint before allowing it to cool below the specified temperature. Always deposit enough weld to prevent cracking before allo�ng a joint to cool. Do not allow preheat and inte�pass temperatures to exceed 400°F for thickness up to 1-112 in, and 450°F for greater thicknesses.

Preheat base metaf to at least 70°F when the base metal temperature is below 32°F. and maintain this minimum temperature during welding. Preheat base metal to 200°F before starting to weld if it is moist, Preheat fracture-critical applications in accordance with AASHTOIAWS D1.5. 4.3.5. Welding Practice. Use an approved procedure to control shrinkage and distortion. Weld FCAW in accordance with an approved WPS. Weld as required by the Contract or erection drawings. Do not change the location or size of welds without approval. Do not make temporary welds for transportation, erection, or other purposes on main members except as shown on the plans or approved, Use a crayon, paint, or other approved method to mark each graove weld to identify the welder who performed the Hrork, Use the stringer-bead technique where possible for groove welds. Progress upwerd in vertical welding passes using a back-step sequence keeping the end of the low-hydrogen electrode contained within the molten metaf antl shield of flux unless the electrode manufacturer's specifications indicate otherwise, Begin and terminate groove wefds at the ends of a joint on extensian bars, Make edge preparation and thickness of extension bars the same as that of the member being welded but extending at least 2 in. beyond the joint. Remove extension bars v�th a cutting torch or arc-air gouging, and grind the flange edges smooth after the wreld is completed and cooled. Clean any defects exposed by the grinding, fill them with weld metal, and regrind them to a uniform finish. Gnnd so that gnnd marks are parallel to the flange, and avoid excess grinding oF the parent metal. Clean and fuse tack welds thoroughly with the final weld. Remove defective, cracked, or broken tack welds. Gouge, chip, or otherwise remove the root of the initial weld to sound metal for all groove welds, except those produced with the aid of backing or those on steel piling or armor joints, before welding is started on the second side. Clean the back side thoroughly before placing the backup pass. Fuse the weld metaf � GLf3 thoroughly with the backing, and use backing that is continuous for the full length of the weld. Make a continuous length of backing by welding sho�ter sections together only under the following conditions: All splices in the backing are complete joint penetration (CJP) groove welds made with the same controls as similar CJP groove welds in the structure, The welds are radiographed and examined as described in Section 448.4.3.7., '°Radiographic Inspectian" to ensure weld saundness. All welding and testing of the backing is complete before the backing is used to make the structural weld. 4.3.5.1. High-Cellulose Electrodes for Root Passes. E7010 and E8010 electrodes may be used when welding the root passes of beam and girder splices if the u�rk is preheated in accordance with Table 4. Remove the E7010 or E8010 electrode pass completely by arc-air gouging, and replace it using a low-hydrogen electrode after the root passes are backed up. 4,3.5,2, Welding Sequence. Make beam and girder splices using the sequences shown in Figure 6. (Some members will require fewer or more passes than Figure 6 shows.) Alternate welds from Flat to overhead to prevent heat buildup alang bevel edge. Arrange the passes between the top and bottom flange to maintain balance and symmelry. Place passes 1, 2, and 3 in the top flange, followed by passes 4, 5, and 6 in the bottom flange (see Figure 6} for rolled I-beams and built-up girders. Gouge out and replace passes 1 and 4, which always are placed in the overhead position. Next, place passes 7, 8, and 9 in the top flange, followed by passes 10, 11, and 12 in the bottom flange. Continue with placing passes 13-17 in the top flange, followed by passes 1�22 in the bottom flange. Continue to alternate welding between top and bottom flange �th a maximum of 5 passes per Flange until the flange splices are complete. Tack weld web after aligning girder webs Nnth short tacks as required to obtain proper alignment. Place pass 23 and pass 24 on the web. Gouge out and replace pass 23. Finish web splice with pass 25. Remove all slag for each layer, bead, and the crater erea, and clean the weld and adjacent base metal before �Iding over previously deposited metal. Avoid are strikes, and if they occur, grind resulting cracks and blemishes out to a smooth contour, checking them visually to ensure soundness.

Conduct radiographic testing (RT} as required in the field at the expense of the Contractor by an agency or individual registered and licensed to perform industrial radiography. Follow all applicable rules and regulations for radiographic operations. Tes6ng includes fumishing all materials, equipment, tools, labor, and incidentals necessary to perform the required testing. The Department may reguire fu�ther tests in accordance with Article 5.10., '°Inspectian," and may perform additional testing, including other methods of inspection. Perform RT in accordance with AASHTOIAWS D1.5. The Engineer �II examine and interpret the resulfing radiographs in accardance �th AASHTOIAWS D1.5. All radiagraphs become the property of the Department and remain with the Engineer. Radiographically inspect the full flange width of all flange splices and the top and bottom 116 of the web at each splice for field-welds of splices in beams or girders. Radiographically retest repaired welds. Make necessary repairs before any further work is done. Additional RT required because oi unacceptable welding or poor radiograph quality is at the Contractor's expense. RT of particular welds required by the plans is in addition to the RT required by this Item. Meet the requirements specified in Section 441.3.2.5.1., "Radiographic TesGng" for radiograph film quality. 4.3.8. CoRections. When welding is unsalisfactory or indicates inferior workmanship, the Engineer rMll require corrective measures and approve the subsequent correctians. Use oxygen gouging or arc-air gauging when required to remove pa� of the weld or base metal. Back-gouge splices in beams and girders or cut out defective welds using arc-air gouging by a welder qualified to make beam and girder splices. Slope the sides of the area to be welded enough to permit depositing new metal were corrections require depositing additianal weld metal. Use a smaller electrode than that used for the original weld where corrections require depositing edditional weld metaf. Clean surfaces thoroughly before re-welding. Remove cracked welds completely and repair. Remove the weld metal for the length of the crack if crack length is less than half the length of the weld plus 2 in. beyond each end of the crack, and repair. Restore the original conditions where wo�C perfonned after making a deficient weld has made the weld inaccessible or has caused new conditions making lhe correction of the deficiency dangerous or ineffectual by removing welds, members, or both before making lhe necessary corrections; atherwise, compensate for the deficiency by performing additional work according to a revised and approved design. Cut apa�t and re-weld improperly fitted or misaligned parts. Straighten members distorted by the heat of welding using mechanical means or the carefully supervised application of a limited amount of localized heat. Do not let heated areas exceed 1,200°F as measured by temperature-indicating crayons or ather approved methods for steel up to 65,000-psi yield strength. Do not lel heated areas exceed 1,100°F for higher-strength steels. Keep parfs to be heat-straightened substantially free of stress from extemal forces except when mechanical means are used with lhe application of heat. Befare straightening, submit a straightening procedure to the Engineer for approval. Carrect defective or unsound welds either by removing and replacing the entire weltl or as follows: 4.3.8.1. Excesslve Convexity. Reduce to size by grinding off the excess weld metal, leaving a smooth profile. 4.3.8.2, Shrinkage Cracks, Cracks in Base etal, Craters, and Excessive Porosity. Remove defective portions of base and weld metal down to sound metal, and replace with additional sound weBd metal. � 4.3.8.3. Undercut, Undersize, and cessive Concaviry. Clean and deposit additional weld metal, 4.3.8.4. erlap and Incomplete Fusion. Remove and replace the defecGve portion of weld. 4.3.8.5. Slag Inclusions. Remove the parts of the weld containing slag, and replace them with sound Id metal. 4.3.8.6. Removal of ase etal during elding. Clean and form full size by depositing additiona! weld metal using stringer beads. 4.4. Shear Stud elding. Weld shear studs to steel surfaces and perform preproductian and production tests as required in AASHTO/AWS D1.5. 4,5. elding Reinforcing Steel.

Additional Requirements for Type B Cable Materials. Additional material requirements particular to Type B cable are as follows: � Ensure cables consisting of 5 or more conductors have a 0.25-in. nominal diameter messenger. For the messenger, use Class A galvanized Extra High Strength Steel Strand with 3 or 7 wires. A solid strand messenger with 0.134-in. diameter may be used for cables with less than 5 conductors. � To provide corrosian protection, ensure the messenger strand is coated and the interstices are flooded with a rubber asphalt compound or equivalent. Ensure the integral messenger and conductors are enclosed in the jacket forming a cross-section similar to a figure 8. 2.6. Type C Cable aterials. Use ihe follo�ng materials for Type C cables: Unless other�se shown on the plans, use No. 14 AWG insu6ated conductors with concentric stranding with black insulation on 1 of the 2 conductors and clear insulation on the other conductor. Ensure conductors have a minimum of 2 twists per foot within the cable. Use cables that have 100% shield coverage using aluminum bonded to a Mylar film. Ensure the drain wire is stranded tinned copper, 2 AWG sizes less ihan the conductor, and in continuous contact �th the aluminum side of the shield material. Ensure the jacket is black polyethylene. Use cables that legibly show the name of the manufacturer and the IMSA specification number applied at approximate 2-ft. intervais on a tape under the outerjacket. 2.7, Sampling. The Engineer may take samples fram each roll of each size of cable for establishing conformity to IMSA. The samples will be at least 3 ft, long. Replace any cable failing to meet IMSA requirements. • • For each cable run in underground conduit, coil an extra 5 ft. of cable in each graund box. Splices are not permitted in Type A and B cables unless shown on the plans, or approved in writing. Ensure splices are watertight. 843 C�l 1 ��, �� " 1 ' f� ��'. . � ': . 1 1 t I, � ' " 1'. ; � ,"...
