The finish course of a parking lot, following the binder layer, should be a smaller and smoother stone at 1.5" thick for a total of 3". For heavy duty traffic like, trucks, loading docks, or roadways, we recommend a 2" finish layer on top of the 2" binder for a total of 4". Light Duty Parking Lots vs. Heavy Duty Parking Lots:

The older major arterial roads however recorded lower average asphalt layer thickness range of 74 - 90 mm for the designed thickness of 150 mm and showed a RMSD of ±24 mm . The lower average asphalt layer thicknesses recorded in this case may be attributed to the relative compaction of these older pavements over the years.

The layer thicknesses stagger depending on the material and type of the road between 5cm - 12cm. III. Top layer The top layer is the most heavily used layer of the road, because it is subject to the direct influence of traffic, weather and thawing agents. Thus, the top layer must be particularly resistant to wear and deformation.
