Abstract

Abstract

In order to prevent the early destruction of highway, provide theoretic analysis and technology support for the study of long life pavement structure, the thermal field and fatigue stress of asphalt concrete and continuously reinforced concrete(AC+CRC) composite pavement were analyzed by finite element method. Analysis result shows that the asphalt concrete layer with less than 4 cm thickness is mainly used to improve pavement performance, while the asphalt concrete layer with more than 4 cm thickness can improve pavement thermal field effectively, every adding 2 cm asphalt concrete can meet 15%~20% overload. It is indicated that the composite pavement can withstand heavy load and overload to a certain extent to avoid pavement fatigue destruction.
