Abstract
Since it exist a significant difference in stiffness between asphalt surface and lean concrete base layer,the probability of shearing failure increase.In this paper,a typical structure of asphalt pavement with lean concrete base is established,selecting smooth state as the interfacial contact condition.BISAR3.0 is used to calculate stresses in the multilayered elastic system.Results display that the thickness of asphalt layer and the load condition have an enormous influence on shear stresses,while surface modulus,the modulus and thickness of base layer do not much affect the shear stresses in surface.
