Investigation of Fracture Behavior of Recycled Asphalt Mixtures Using a Discrete Element Computational Model
A discrete element computational model is used to simulate the fracture behavior of asphalt mixtures, containing different RAP proportions, at low temperatures. In this model, coarse aggregates are explicitly represented by rigid spherical particles. The bonds that connect these particles represent the fine aggregate matrix (FAM), which is defined as the combination of asphalt binder and fine aggregates. The model is used to investigate the fracture behavior of four asphalt mixtures with different RAP contents. Semi-circular bend (SCB) fracture tests are performed on the asphalt mixtures and bending beam rheometer (BBR) strength tests are performed on FAM at low temperatures.
