PERMANENT DEFORMATION CHARACTERIZATION OF BITUMINOUS MIXTURES FOR PREDICTING PAVEMENT RUTTING

A general overview of rutting models available for predicting rutting in flexible pavements, the permanent deformation characterizations used by these rutting models or subsystems, and the general limitations of these characterizations is given. Discussed in detail are VESYS and DEVPAV. The most intensive development of a rutting model has been for the VESYS subsytem through support of the Federal Highway Administration. Since numerous researchers are involved in its further development and implementation, the published results of permanent deformation testing by a number of researchers have been transformed to the VESYS material characterization parameters ALPHA (1) and GNU (1). The relationships between these and other significant variables such as deviator stress, temperature, resilient modulus, and confining stress are reviewed and summarized. ALPHA(1) and GNU(1) were found to generally decrease with increasing deviator stress or temperature; the increase in ALPHA(1) dominated the effect on permanent strain predictions. ALPHA(1) increases with increasing confinement, and GNU(1) appears to decrease. Both parameters appear to increase as the material stiffness increases. (Author)
