Abstract:
In order to analyze the temperature stress of the porous concrete base layer of asphalt pavement, a three-dimensional finite element model of asphalt pavement of porous concrete base layer was established. Through numerical calculation method, the temperature field of asphalt pavement of porous concrete base layer was analyzed, and the maximum temperature gradient variation range in each natural zone was proposed. The effects of surface thickness, thickness and modulus of porous concrete base layer and foundation modulus on temperature stress were studied. The calculation results with the same conditions are comparatively analyzed, and the results show that the temperature stress of the base layer decreases with the increase of the surface thickness, increases with the increase of the base layer to the foundation modulus ratio, and increases with the increase of the base layer thickness.
