Repeated in adverse weather conditions and vehicle loads , asphalt pavement permanent deformation or rutting is one of the characteristics of its typical broken ring . In this paper, based on the analysis of the current use of the grading curve , select five typical grading curve toward the system test , obtained the five -level distribution toward the sort of high-temperature performance . Flat slender particle content of different gradation type of asphalt mixture rut resistance , given its preliminary threshold values ??. Mobile asphalt concrete aggregate particles in the load process trajectory study from the microscopic point of view , to explain and describe the causes permanent deformation of asphalt mixture and its development process , and provide ideas for further microscopic quantitative research . Rutting test and immersion rutting test under different temperature and load , harsh climate and traffic conditions as well as high temperature and water coupling on the asphalt mixture rut resistance . The article also flooding rutting test for different combination of the pavement structure and materials investigated and compared the formation and development of the extent of its rut .
