Abstract: In recent years, with the development of China's transportation construction industry, the number of new, rebuilt, and expanded pavements has increased, and various combinations of pavement structures have appeared. Most pavement structures are designed according to the mechanics-empirical method, and the design parameters of pavement structure and design road performance are designed based on experience. Therefore, various scientific research and testing institutions of higher education institutions and MLS66-type accelerated loading equipment imported from abroad have done a lot of research on the durability evaluation of China's pavement structure. The main research directions are: the mechanical response research of steel bridge deck paving, the pavement structure strain research, and the pavement structure performance research of overlay pavement. These research results have important application value.
