Abstract: Porous pavements provide superior skid resistance, lower traffic noise and improved runoff quality. These benefits result from their high porosities produced by uniform-size aggregates. Experiments have been developed to evaluate porous pavement performances, while numerical studies are still limited in literature. This work adopts a simplified pore network model to analyze the influences of pore size on the permeability and skid resistance of porous pavements. After reviewing relevant studies, this paper introduces the developed simulation models first. Permeability and skid resistance tests on porous pavements with the same porosity but various pore sizes are next simulated and analyzed. It is found that despite the identical porosity, pavement with a larger representative pore size provides higher permeability and superior skid resistance performance. However, the influences of pore size on porous pavement properties are found to be marginal. Pore size may not be a crucial parameter in porous mixture design. © 2014 Taylor & Francis Group.
