Analysis of the Dynamic Response for Saturated Asphalt Pavement under Moving Vehicle Loads by Three-Dimensional Finite Element Method

Rui Ren, Li Tao Geng, Wen Qi

Abstract

The dynamic response of saturated asphalt pavement subjected to moving vehicle load is studied. Based on the porous media theory, a three-dimensional finite element model is developed and the temporal and spatial distribution of three directional stresses and strains are calculated in saturated pavement and compared with those in dry condition. The results show obvious difference between saturated and dry asphalt pavement, especially in asphalt layer.
