(3) Subgrade: the material of the ordinary dense gradation asphalt pavement is usually the clay, sand and stone.
According to the simulation of heavy rainfall infiltration in permeable pavements , the results illustrated that because of using macropore asphalt material, pervious pavement has large porosity, high permeability, and rapid rainwater infiltration.

Thus, for better understanding of these phenomena, thermomechanical processes should be examined not only in the thin material layer in the vicinity of the friction surface but also in the whole element[5, 6].
Fig.5 Temperature experimental result during braking Fig.6 Von Mises stress distribution The calculated maximum values of the Von Mises stresses had reached about 408MPa, which does not exceed the yield stress of the materials used in the discs, as shown in Fig.6.
This may suggest that the deformations are the result of material creep at elevated temperatures.
