Biphasic asphalt concrete consists of mineral aggregates and a surrounding bituminous binding agent, of those material properties are known. To obtain the overall material behavior, we generate Statistical Volume Elements (SVE) of the asphalt concrete structure artificially. Afterwards, the Nonuniform Transformation Field Analysis (NTFA) is applied to homogenize them. This paper focuses on the stochastical differences of the microstructures of the SVEs and their influences on the macroscopic material behavior. Therefore, an indirect tensile test is simulated.
