WebHMA Layer Rutting Within the MEPDG, the only way to decrease the predicted rutting within the HMA layers of a pavement is to increase the dynamic modulus of the mixture. The E* AMPT Specification Criteria Program, described in NCHRP Report 580, can be used to determine the minimum dynamic modulus needed to keep the predicted rutting below a ... WebWheel-tracking results showed that rut depth decreases significantly with LDPE incorporation and aging improved rutting resistance. Comparing HMA and WMA, the latter performed worse in the cyclic compression test and better in the wheel-tracking test. LDPE incorporation increased the accumulated strain (ε3600) and decreased the creep rate ...
