ABSTRACT

The introduction of several observation scales within the multiscale concept allows to account for different mixture compositions of multi-composed materials such as asphalt mixes. Moreover, changes in the characteristics of constituents resulting from mechanical loading and/or environmental conditions can be considered at the respective observation scale. Within multiscale models, the effect of such changes on macroscopic material properties is obtained by scale bridging, i.e. upscaling of information from the finer scales to the macroscale. In this paper, the latest advances in the development and application of a multiscale model for asphaltic materials are presented (see Figure 1).
