Abstract: Our country has built highways for the semi-rigid base asphalt pavement structure, the structure bearing capacity is strong, rut depth is small, good water stability, and has become the main structural type of high grade highway in China. But the practice has proved that there are some inevitable semi-rigid base asphalt pavement of technical problems, in a number of highways open to traffic soon after the pavement early damage phenomenon more serious, such as rutting, and vertical and horizontal cracks, cracks and potholes, local loose aging, seriously affected the normal traffic, but also violates the highway within the use fixed number of year is not for the purpose of the large maintenance. This paper analysis the properties of cementitiously stabilized materials linked to pavement performance, summing up the experiences of domestic and foreign research and related pavement distresses and the fatigue of CSL and related pavement distresses, stiffness of CSL and related pavement performance and erudibility, to do researches for the development of the improvement of the pavement.
