The first step in building a lasting parking lot is to remove the existing blacktop.
After that is complete and the old asphalt is disposed of properly (see section on Recycling Services), the contractor inspects the sub-base and determines whether or not it needs to be removed and replaced.
If new sub-base is needed, 6 to 8 inches of R1 Type RCA will be installed and compacted.
After the base is compacted and settled, 2 to 3 inches of Type 3 binder is laid and compacted.
Following the installation of the binder, 1½ to 2 inches of Type 6 or Type 7 top is laid and compacted.
