Abstract

In this study, a finite element (FE) model was adopted to simulate the rutting performance of different asphalt mixtures, using commercial general-purpose FE package, ANSYS. The FE model representing the results included two main properties: the viscoelastic properties, which are represented by Poisson’s ratio and the dynamic modulus (E∗), and the plastic properties, which are represented by the time-hardening creep parameters. Data and results generated from the FE model were put in comparison with those obtained from the asphalt pavement analyzer (APA) test, which showed satisfactory level of accuracy in simulating the rutting behavior. In addition to this, statistically analyzed results indicate a proportional correlation between the number of loading cycles and the accuracy of the obtained FE model results. Thus, it is recommended to use a minimum loading cycle of 2000 when analyzing rutting using the FE model.
