Viscosity restrain the road performance of asphalt mixture with geothermal regeneration. In the design and construction of the geothermal renewable asphalt pavement, the thickness of the regenerated layer is one of the most important factors that affect the mechanical response of the material. In order to improve the road performance of the heat recovery asphalt pavement, ANSYS finite element analysis method is adopted to build the 3D model of asphalt pavement structure, and then the asphalt road structure of each layer is also analyzed. The change law of the thickness of the regenerated asphalt layer and the road surface deflection, and the thickness of there generated layer and the residual deformation are obtained. Moreover, the relationship between the thickness of the asphalt regeneration layer and the bending stress of the base is obtained, too. It is found that the thickness of the regeneration layer can reduce the damage of road structure layer, which lays a theoretical foundation for the design and construction of geothermal renewable asphalt pavement. And it can provide an idea for the viscoelastic mechanical response of recycled asphalt concrete pavement.
