Computerized Analysis of Flexible Pavement Rutting Behavior (PAVRUT)

摘要

Rutting is one mode of failure in flexible pavements. Described herein are laboratory models that predict rutting in asphaltic concrete, dense-graded aggregate, and a subgrade soil. These models have been programmed to predict a rut depth for a particular pavement structure using a given set of traffic and environmental conditions. A number of rutting charts have been developed and are presented herein that can be used to estimate rutting in a particular structure after an assumed number of equivalent axleloads. These charts can also be used for overlays on flexible and rigid pavements.
