Development of a Computational Model for Asphaltic Concrete Response under Cyclic Loading

When traffic load is imposed on a pavement, a non-uniform displacement field develops giving rise to a multitude of triaxial states of stress. Triaxiality has been known to significantly influence the response of asphaltic materials. In this contribution the extension of the Desai plasticity based material model for reversed cyclic loading is presented. Hardening of the material is simulated via a mixed hardening formulation. In order to enable a smooth elastic-plastic transition, the bounding surface concept proposed by Dafalias and Popov is utilized.
