Abstract:Cement grouting semi-flexible asphalt pavement is a pavement of grouting a certain amount of cement mortar into the macrovoid asphalt concrete so as to form a pavement with stiffness between asphalt pavement and cement pavement. The structural design theory and parameter, and structural composite design of semi-flexible pavement, and the material design of the important components of matrix asphalt mixture and cement grouting of semi-flexible pavement are summarized. The way-use performance of semi-flexible pavement is analyzed. The study progress of low-temperature cracking problem of semi-flexible pavement and the problems to be solved in recent years are specially summarized.
