Numerical Observation of Damage and Cracking Behavior in Three-Point Bending Asphalt Mixture Beam

Abstract:

This paper presents a damage constitutive model to characterize the softening behavior of asphalt mastic in the fracture process. The three-point bending asphalt mixture beams with different crack locations and aggregate distributions are modeled with the parameterization modeling method. It is found that there is good agreement between the predicted and experimental results. The effects of crack location and coarse aggregate distribution on the crack path are numerically evaluated, and damage distributions near the crack tip are analyzed. Some conclusions are given.
