【Abstract】 In this paper, the actuality of predicting method of rutting in asphalt pavement is summarized and evaluated. Based on the progress of development of predicting method of rutting in asphalt pavement, the direction of further development is researched. Moreover, the application of viscoelasticity finite element theory and method is particularly introduced. The examples indicate the predicting results by this method are highly reasonable with the experimental data. So, it is testified that viscoelasticity finite element method(FEM)is very effective to predict the rutting phenomenon in asphalt pavement.更多还原
