Abstract For evaluating the water stability of hot-mixed renewable asphalt mixture (HRM), the traditional methods are all
tested under still water conditions. Except for damage in still water conditions, the hydrodynamic pore pressure
generated by the tire driving on the surface water has a great impact. Thus, the RAP contents of the HRMs were
designed at 0%, 30%, 45% and 60% with AC-25 gradation. Then, the self-designed evaluation methods of water
stability and dynamic modulus were studied. Finally, the mechanism of the influence of hydrodynamic pore pressure damage on HRMs was studied. The results show that… More >
