The thckness design of the pavement is the determination of the overall thickness of the road and the thickness of the individual layers. This is of course dependant
Asphalt pavements are typically placed in "lifts," or layers for a total compacted thickness of 3 or more inches. For example, a total of 3 inches may be placed in two layers each 1.5 inches thick when compacted. A good way to pave a 4-inch pavement is to first place about 3 to 4 inches of loose asphalt, and compact it to a thickness of 2.25 to 3

The thickness of a parking lot depends heavily on the amount and type of traffic of that specific lot. For standard commercial jobs, the dense-graded aggregate layer is typically about 8” thick. On top of the base, we typically recommend applying two 1.5” layers of asphalt. The first binder layer of 1.5” would be a thicker stone.
For heavy duty traffic like, trucks, loading docks, or roadways, we recommend a 2” binder layer. Asphalt Thickness: Residential – Asphalt driveways need to be a minimum of 2” thick and are typically 3” (compacted). Commercial – The finish course of a parking lot, following the binder layer, should be a smaller and smoother stone at 1.5” thick for a
