A micro-fabric distinct element modeling (MDEM) approach was implemented in the two dimensional particle flow software package (PFC-2D), to study the complex crack behavior observed in asphalt concrete fracture tests. This behavior was simulated with an MDEM model having complex morphological features. To verify the bilinear cohesive zone model (CZM) implementation, the double cantilever beam (DCB) was analyzed. It was found that the numerical results form the simulations compared favorably with the analytical solution, and the trends in initial stiffness, peak load and corresponding CMOD matched well with experimental results.
