Aimed at structure characteristics and the flaws of existing studies of continuous reinforced concrete and asphalt concrete (CRC+AC) composite pavement, some different data were calculated by using fracture mechanics theory and finite element method (FEM), including the maximum temperature gradient of CRC layer, the rutting depth and the thermal crack propagation strength, and the relations between the structure layer thickness and these data respectively were analyzed. Results show that when the thickness of AC layer is not less than 4 cm, the maximum temperature of CRC layer top surface can ...
