Abstract

This paper investigates the effects of subgrade stiffness and stiffness transition on mechanical responses of asphalt pavement using multiple layered elastic analysis and three-dimensional finite element modeling. The surface deflections and internal stress distributions were analyzed by numerical simulation. The maximum shear stress was used as the indicator to determine the stiffness threshold for subgrade at bridge approach. It was found that the mechanical responses of asphalt pavement were very sensitive to the variation of subgrade stiffness. The stiffness of subgrade at bridge approach should be controlled more than 500 MPa, and the stiffness transition is better to follow an exponential function to ensure the uniform stress distribution of pavement structures. Considering engineering practice and cost factor, a reasonable stiffness range of 1000 MPa–2000 MPa was recommended for the subgrade at bridge approach.
