Finite Element Analysis of Asphalt Overlays on Existing PCC Pavement under Heavy Traffic Loading
This study models the thermal stresses and load stresses of Xia-Feng expressway asphalt overly on an existing PCC pavement by using finite element method. The sensitiveness of different influence factors on thermal stresses and load stresses are discussed. Research results show that asphalt overlay deflection and load stresses increase with the decreasing of weakening of subgrade strength index λk and when a soft interlayer with low level of spring stiffness is adopted, the thermal stress of asphalt overlay is quite small compared with load stresses.
