摘要：

Aiming at the shortage of design life and actual life of pavement, considering the design of long-life pavement, this paper analyzed the structure stress and temperature stress of PCC+AC composite pavement based on three-dimensional isoparametric element and elastic layer system theory through ANSYS, and expounded the mechanics pattern of PCC+AC composite pavement, an actual highway with PCC+AC long-life pavement was constructed to test the life of the composite pavement. The result shows that: the main factors affecting load stress and temperature stress of PCC board are the thickness of cement concrete board and the concrete modulus and thickness of asphalt concrete, but the modulus of asphalt concrete affects temperature stress of PCC board hardly; the life of the composite pavement is over 40 a. 5 tabs, 4 figs, 7 refs.
