Numerical Simulation of Fracture at Asphalt Mastic Materials

In this paper, numerical simulations have been conducted to investigate how damage initiates and propagates at mastic materials. Mastic is known as the matrix component of asphalt concrete. The 2D specimen digital model has been created by using a layer of mastic material which is inserted between two coarse aggregate. Cohesive elements have been inserted into mastic to simulate crack initiation and propagation. The effects of loading and stiffness modulus will be investigated. Many important conclusions will be given.
