A Model for Behavior Prediction of Asphalt Mixtures

Document Type : Research Article



The vehicle load repetition on the pavements leads to further deflections due to the material softening and the reduction of pavement stiffness. In this research, the stiffness reduction studied using a back analysis of surface bowls under wheel load. In this back analysis the visco-elastoplastic model and the finite element method used. There seems to be no evidence of evaluating the stiffness reduction of pavements using visco-elastoplastic modeling of asphalt concrete behavior. The results indicated that this modeling approach provides a more accurate predication of performance and useful cycle life of asphalt mixtures  when compared to the visco-elastic models.
