In this contribution, a finite element tool which is developed at Delft University of Technology, for the simulation of combined physical-mechanical moisture induced damage in asphaltic mixes is presented. Processes that are included as important contributors to moisture induced damage are molecular diffusion of moisture and a 'washing away' process of the mastic, due to a pumping action of the traffic load. In the model, these physical material degradation processes interact with a model for the mechanical damage to produce the overall moisture-mechanical damage in the mix. This contribution shows the model, discusses the dominant material parameters and gives a numerical example.
