| With the development of social economy, the passengers and cargo transportation is increasing rapidly, especially the increasing of heavy vehicle and using of high pressure tyre, rutting damage of asphalt pavement has become one of the most main diseases in high-temperature areas, all of this is becoming a cause for concern. This paper make an investigation on surface course,middle course and lower course, analysis on the influence factors of the high temperature stability of asphalt mixture.First, paper make an investigation on Guangshao pavement, traffic volume and damage conditions is obtained .Through prefer the value which rutting can be permit, rutting situation of pavement is evaluate. Vary of each layer is gained through measure thickness of each course, from this we can find reason of rutting.Though wheel tracking test obtain experiment date, analysis these experimental results using variance analysis and correlation analysis, degree of impact of surface course,middle course and lower course was attained. Though establishes the actual road surface wheel rut depth model, dynamic stability target of lower course(AC-25) was obtained.Through extraction test on the sample, asphalt mixture gradation of pavement was obtained. Compare gradation of deferent position, then take construction guideposts of structure level.Principle and main influence factors of the formation of rutting is analyzed in this section, compare the degree of influence of asphalt-aggregate ratio,the percentage of 4.75 sized aggregate passing through the screen,powder content and Air voids in asphalt mixtures on themal ability of asphalt mixture, using Gray correlation analysis.Environment is very important influence factors on rutting damage of asphalt pavement. Three temperatures test points along the route of pavement was selected to install, in order to measure pavement temperature of different depth, through analysis of these date, pavement temperature field change rule can be find.
