Abstract

The vehicle load action often leads to serious damage of saturated asphalt pavement. The finite element model of saturated asphalt pavement was established by ANSYS to research mechanics behavior of pavement response to moisture-loading coupling action. Then, the spatial distribution of pore-water pressure, vertical displacement and shear stress of saturated asphalt pavement was analyzed. The results indicate that the stress field and displacement field changed a lot, the positive and negative change of pore-water pressure will result in stripping of asphalt mixtures. The vertical displacement variation of each layer structure is basically the same, and the shear stress is mainly concentrated on the area around the intersection of lower layer and grassroots which may result in rutting damage.
