DETERMINATION OF THE LAYER THICKNESS FOR LONG-LIFE …

Results demonstrate that the pavement greater 410mm of total AC layer thickness is considered as the long life pavements regardless of the material characteristics and thickness in each layer.

Determination of the Layer Thickness for Long-Life Asphalt ...

To become a long life pavement, a total thickness of AC layer should be greater than 250mm. The design procedure for determining the layer thickness and modulus of the pavements with AC layer thickness ranging from 250 to 410mm is also presented in this paper.

Asphalt Pavement Guide: Thickness | EastCoat Pavement …

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 …
