Abstract

This paper presents a systematic and straightforward analysis procedure to extract the material parameters associated with a coupled nonlinear viscoelastic (VE), viscoplastic (VP), and hardening-relaxation (HR) constitutive model for asphalt mixtures. The recoverable and irrecoverable strain are represented by Schapery nonlinear VE model and Perzyna-type VP theory, respectively. A HR model is proposed to consider the relaxation of hardening. Dynamic moduli and repeated creep-recovery tests are used to calibrate the coupled VE-VP-HR model. The model is then validated against independent experimental data. Results show that the VE-VP-HR model has the ability to capture the response of asphalt mixtures subjected to various loading paths.
