Abstract:In this study, a modified two-phase micromechanical model (MTPMM) and a generalized self-consistent model (GSCM) considering voids effect in the asphalt concrete are both adopted to predict asphalt mixture E*. It is found that the equivalent Poisson’s ratio of asphalt mixture is of vital importance for prediction accuracy of the MTPMM. Analytical results from both MTPMM and GSCM matched well with the experimental results. However, the GSCM underestimates E* in the lower loading frequencies while overestimates in higher loading frequencies. The numerical solution from the random aggregate mode
