Define Pavement Design - Transportation
1. Asphalt surface
a. Estimate Design Traffic
b. Determine the Structural Number (SN) for the given traffic, roadway, and soil characteristics
c. Compute layer-thickness using the following equation
SN = a1D1 + a2D2 + ...+anDn
Where SN = structural number of the pavement
ai = strength coefficient of the ith layer
Di = thickness of the ith layer in inches
