Article Preview

The combined effect of moisture and dynamic loading on asphalt mixtures has been recognized as one of the main causes of premature deterioration of flexible pavements. Based on porous medium theory, the asphalt mixture is regard as saturated porous material, and a three-dimensional finite element model is established to investigate dynamic response of two typical asphalt pavement structures, which are the semi-rigid asphalt pavement and the semi-rigid asphalt pavement with flexible base course. Then the spatial and temporal distribution of stress, strain and pore fluid pressure of the two structures are calculated, respectively. Analysis results show the superiority of semi-rigid asphalt pavement structure with flexible base course to the semi-rigid asphalt pavement in aspect of moisture resistance capability.
