| Abstract: | To overcome serious rut failure on upgrade road section of asphalt pavement in mountain area, by analysis of operational characteristics of vehicle on upgrade road section the calculation of horizontal and vertical loads of vehicle to pavement structure is carried out. Through establishment of three - dimensional finite element model for rad,the paper analyzes impact of vehicle load on structure shear stress of asphalt pavement in mountain area,adopts rational design of structure and qualifications for longitudinal grade, increasing the shear resistance of asphalt pavement in mountain area. |
