| Abstract: | Based on graded gravel bearing plate test this paper establishes formulae of constitutive model of nonlinear bearing capacity of base course materials of graded gravel and builds planar model of typical structure of asphalt pavement with flexible base course by means of ANSYS universal finite element software.The paper analyzes structural stress of asphalt pavement with aggregate base course and semirigid base course,including propagation laws of stress and strain of asphalt pavement with flexible base course under different stress conditions and propagation differences of stress and strain from asphalt pavement with semi-rigid base course. |
