This paper will give a short overview about a multi‐scale modelling approach for bituminous asphalt concrete. The goal is to describe the micro‐heterogeneous medium by a homogeneous surrogate medium, which has similar effective mechanical properties. Starting from the varying constitutive behaviour on the micro‐scale, our up‐scaling procedure is realised via volume averaging techniques. By use of a Finite‐Element model, the results for different types of boundary conditions (BCs) and their influence on the properties of the compund are investigated on the effective scale.
