Computational Micromechanics Modeling for Damage-Induced Behavior of Asphalt Mixtures Considering Viscoelasticity and Cohesive Zone Fracture
This paper presents a model for predicting damage behavior of asphalt mixtures in flexible pavement systems. Experimental protocols to measure material properties and fracture characteristics of mixture components and their incorporation into constitutive models based on the micromechanical finite element analyses are developed and presented herein. The model employs only directly-measured material and fracture properties of small scale mixture components as model inputs necessary to predict damage-dependent behaviour and life of global scale asphalt concrete mixtures that typically show significant heterogeneity and inelasticity. The presented methodology is therefore expected to provide a significant savings in experimental costs and time over traditional approaches.
