本研究では，舗装材料の弾塑性挙動を予測するために，拡張SMP基準と等方硬化パラメータを用いて修正Cam-Clayモデルを改良し，アスファルト混合物，粘性土，粒状路盤材料の静的三軸圧縮試験の弾塑性解析を行った．その結果，実測結果と解析結果は良く一致しており，本研究で提案した弾塑性モデルが舗装材料の静的な弾塑性解析に適用可能であることがわかった．

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.
