Micro Abstract:
Mastic asphalt is a highly heterogeneous mixture consisting of elastic mineral aggregates and of an viscoelastic bituminous binding agent. To obtain the mixture's overall material behavior, we apply computational homogenization and order reduction. We computationally generate statistical volume elements based on real-data from X-Ray Computed Tomography. The resulting macroscopic material model is used to verify the method in comparison to laboratory experiments.
