2019-042 Mayhill Asphalt MillingsDate: March 8, 2019 Report No. 2019-042
INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
Acceptance and use of asphalt millings resulting from the realignment and construction of
Mayhill Road.
BACKGROUND & DISCUSSION:
The City of Denton’s landfill operation is required by permit to maintain its internal roads in a
condition which provides suitable access to disposal sites and other public areas in all weather
conditions. These temporary roads are generally constructed of asphalt millings, crushed
concrete, gravel, or other suitable material. Absent the presence of this material, the City of
Denton is required to purchase such material at approximately $10 per ton. Currently, Solid
Waste’s stockpile of asphalt millings is close to being depleted, and as a result, the operation has
a need for additional millings to maintain the condition of landfill roads.
Zachary Construction recently contacted the Solid Waste Department and offered to deliver
clean asphalt millings to the landfill. Several tons of asphalt are being removed from old Mayhill
Road over the next two to three months, and the contractor has agreed to mill the material, haul it
to the landfill, and either place it directly on a temporary road or stockpile it at the direction of
city staff for future use.
This material differs from existing concrete stockpiles in that it is clean material, meets our
rubble acceptance criteria (<5% contamination), and does not require processing to be put to
immediate use. In addition to the savings realized by Solid Waste, acceptance of the material will
prevent hauling and disposal charges from being incurred as part of the Mayhill Road
construction project.
Unless directed otherwise, staff intends to accept the asphalt millings for immediate use in
internal road construction.
