Abstract

This paper addresses the stability of pavement structures under long term repeated loading using the shakedown theory. The accumulation of plastic strains in a given system may increase under repeated load applications, leading to incremental collapse, or plastic strains may cease to increase with time, resulting in a stable response or shakedown. An improved numerical method using finite element formulation coupled with an optimization technique is introduced. The method takes into consideration the variable elastic coefficients of both the coarse-grained and fine-grained layers in the pavement structure through the application of an extension of the classical shakedown theorem. The proposed method is used to illustrate the influence of layer properties on the shakedown behavior of general pavement systems.
