Abstract

A deformation prediction model for the dynamic creep test is deduced based on the linear viscoelastic (LVE) theory. Then, the defect of the LVE deformation prediction model is analyzed by comparing the prediction of the LVE deformation model with the experimental data. To improve accuracy, a modification of the LVE deformation prediction model is made to simulate the nonlinear property of the deformation of asphalt mixtures, and it is verified by comparing its simulation results with the experimental data. The comparison results show that the LVE deformation prediction model cannot simulate the nonlinear property of the permanent deformation of asphalt mixtures, while the modified deformation prediction model can provide more precise simulations of the whole process of the deformation and the permanent deformation in the dynamic creep test. Thus, the proposed modification greatly improves the accuracy of the LVE deformation prediction model. The modified model can provide a better understanding of the rutting behavior of asphalt pavement.
