Cracking Simulation of Asphalt Mixtures Using a Finite Element Micromechanical Model
Cracking in the surface layer of asphalt pavement has been shown to be a major source of distress in roadways. Asphalt mixture is typically a heterogeneous material composed of aggregates, binder and air voids. Previous cracking studies have not considered the material heterogeneity. Digital Image Processing techniques is a powerful tool to describe the microstructure of the material. A micromechanical cohesive zone model that introduces ductility at the crack tip has been used to simulate the cracking of asphalt mixtures. ABAQUS software is a convenient finite element method to conduct simulations of particular laboratory specimens such as Indirect Tensile Tests(IDT) considering the micromechanical model. Simulation results of the IDT compared favorably with experimental results. Even though this study presented a attempt of a numerical simulation of a simple IDT test, the theory and methods adopted by the study can be applied to the fatigue damage study under the complicated loading considering the material heterogeneity, and then would effectively allow researchers link the micro-scale damage observed on the local scale with the real pavements fail on the global scale.
