Study On The Performance Of Anti Rutting Of Asphalt Mixture

Asphalt mixture has been widely used in highway construction, according to a lot of research, the rutting of asphalt pavement has been the main form of damage, rut disease has seriously affected the using time of pavement. The author read a lot of literature, summarized in the research on the rutting problem in the past, focused on the asphalt pavement structure on the effect of anti rutting performance. This paper attempts to reveal the cause of rutting of asphalt pavement with a new perspective, and suggest reasonable can effectively avoid the rutting of asphalt pavement, reduce the adverse effects of rutting of pavement in a certain extent.The focus of this paper:1, summarized the domestic and foreign research history about this problem, The domestic scholars to the rutting formation and prevention of what good advice.2, to have been built out of the road rut census, identified in the actual completed sections of the rut disease occurrence scope and degree of development. According to census results, for easy happening the rut disease of sections made pertinence research.3, the raw material of the performance comparison test, in order to determine the influence of raw material anti rutting performance of asphalt mixture. Mainly to do comparative tests for four different asphalt, conventional testing some column of this four kinds of asphalt, the contrast experiment on high temperature stability and low temperature stability of asphalt mixture of four in the same grade is composed of. The anti rutting performance they do a detailed observation. Analysis of anti rutting performance of asphalt pavement, through 4 design examples, in this part, in strict accordance with the specification requirements of material testing and grading design, testing related to asphalt mixture forming the. The formation of rutting, pavement 5 contains a variety of reasons, after the actual conditions of the comprehensive, targeted puts forward reasonable suggestions for rutting prevention in the construction of roads, in the prevention of rutting formation on the issue should be considered.
