Multiplicative Viscoelastic-Viscoplastic Damage-Healing Model for Asphalt-Concrete Materials

Balieu, Romain / Kringos, Nicole / Chen, Feng / Córdoba, Enrique

Abstract A viscoelastic-viscoplastic model based on a thermodynamic approach is developed under finite strain in this paper. By introducing a damage evolution, the proposed model is able to reproduce the behavior of Asphalt-Concrete materials until the complete fracture. Moreover, a recoverable part of the degradation is introduced to reproduce the self-healing observed under a sufficiently long rest period. The proposed model is implemented into a Finite Element code and good correlations between the numerical responses and the experiments have been observed.
