There are a multitude of options when it comes to maintaining or repairing your asphalt parking areas. Below you’ll find a quick overview of the more extensive repair options available to you.
Asphalt overlays are a method of paving 2-3” of new asphalt over the existing asphalt. Overlays extend the life of pavement that is still in serviceable condition. Overlays are particularly useful, when the existing asphalt is inadequate in depth. Overlays are a popular approach because of their value.
Ask a DACS Estimator/ Consultants about edge milling to better blend to the existing layout.
First, the sub grade and base materials are graded and compacted to support the asphalt. Then new asphalt is paved generally 4-6″ deep in the parking areas. Drive-lanes or dumpster areas usually paved 6-8″ deep for heavier traffic and vehicles. The asphalt is placed and compacted in lifts to the proper density.
Mill and Overlay (cold planning/asphalt milling) is the process of removing the worn top layer of the existing asphalt by grinding/planning it, and then paving 2-3” of new asphalt on top.
