A study of a typical coarse-graded pavement subject to dynamic loads at saturated conditions was undertaken. Using a coupled finite element analysis based on the theory of mixtures, the influence of permeability and rate of loading on a saturated flexible pavement was performed. The results from this study show that significant pore pressures can occur in coarse-graded mixtures. In addition, the magnitude and distribution of pore pressures were a function of permeability and rate of loading. It is proposed that further study of asphalt skeleton stresses, stripping and layer de-bonding be undertaken.
