Impact of Cement Concrete Slab Modulus on Asphalt Overlay

Hong Yan-hua

Abstract

Design of asphalt overlay on old cement concrete pavement involves many complex and variable factors. Through establishing three-dimensional model using Ansys finite element programming, the impact of the changes of cement concrete slab modulus on the load stress and deflection at the bottom of asphalt overlay is calculated and analyzed, which can provide reference for in-depth research.
