【Abstract】 Based on the Linear Elastic Layer Theory,by using pavement finite-element method and BISAR program to calculate the shear stress,a synthetic database was established.Using the developed synthetic database,the paper studied the regularities of distribution on shear stress in high grade highway asphalt pavement layers.Factors affecting on the shear stress of asphalt pavement were analyzed including the coefficient of horizontal resistance of loading,depth,thickness,elastic module and Poisson ratio of pavement.In addition,this paper put forward the determination and evaluation method of shear strength,and some suggestions and measures to the asphalt pavement from shear failure.更多还原
