Sep 09, 2015 · Flexible pavements will transmit wheel load stresses to the lower layers by grain-to-grain transfer through the points of contact in the granular structure (see Figure shown below). Load transfer mechanism. The wheel load acting on the pavement will be distributed to a wider area, and the stress decreases with the depth. Taking advantage of
