Abstract
HMA/PCC composite pavement is a new type of durable pavement structure which is a rigid-flexible combination. The composite pavement structure with excellent design has better durability. However, due to less domestic use, there is no effective structural combination design method in china. In this paper, a new structural design method of HMA/PCC composite pavement is put forward, in which the maximum thickness of asphalt concrete is designed according to the allowable permanent deformation, and the lower limit of the thickness of asphalt concrete is designed with the allowable shear stress of bond layer as the index. The composite slab model was used to design the thickness of concrete layer.
