determine the thickness of flexible pavement


Determine the thickness of flexible pavement layer 2 given the following:

 FACTS:

Total Structural Number required = 7.0

Total number of layers = 2

Layer 1 consists of asphalt concrete with a strength coefficient of 0.46

Layer 1 thickness = 6 inches

Layer 2 consists of granular base with a strength coefficient of 0.15 

Answer - SN - D1a1 + D2a2

D2 = SN - D1a1 / a2 = (7.0 - 6 * 0.46) / 0.15 = 28.3"
