In this study, in order to predict elastoplastic performance of pavement materials, the modified Cam-Clay model was revised using the expanded SMP criterion and an isotropic hardening parameter. And the elasto-plastic analysis of triaxial compression test was carried out using the experimental results for a asphalt mixture, some cohesive soils and a granular base course material. As the results, it was confirmed that analytical results agreed well with the experimental results. Consequently, it was proved that the elasto-plastic model proposed in this study is applicable for the static elasto-plastic analysis of pavement materials.
