Asphalt concrete is a complex mixture appearing as a biphasic material containing mineral aggregates and bitumen and as a triphasic material containing voids in addition . Because of that, the overall material behavior of the asphalt concrete cannot be obtained easily from the known material data of its components and therefore, we apply computational homogenization based on statistical volume elements (SVEs). These SVEs are assumed to be statistically representative to obtain the material properties by finite element simulations and homogenization. We generate these microstructures computationally based on data from XRCT scans. The artificial microstructures show reduced geometrical complexity and therefore, reduced numerical costs compared to direct numerical simulations based on XRCT data.
