Abstract

Semi-flexible pavement is a new type of composite pavement formed by filling cement-based grouting material into asphalt mixture with large void. Semi flexible pavement has the advantages of good bearing capacity and strong shear deformation resistance, and is an effective means to solve rutting problems at intersections, bus stops, and other road sections. From the current usage situation, this type of road surface performs well in terms of resistance to rutting. However, in the construction and application process in the northern seasonal freezing zone and wide area conditions, traditional materials and structural design may exhibit varying degrees of top-down cracks, longitudinal joints, and a small amount of surface looseness. In this paper, the structure and mixture ratio of semi-flexible pavement are designed, the performance of semi-flexible pavement is evaluated, and the causes of loose diseases of semi-flexible pavement are analyzed in combination with engineering examples, and relevant maintenance and treatment measures are proposed to provide reference for the implementation of similar projects.
