Abstract: For OGFC-13, by rutting experiment under different saturated water rate, the rutting resistance of porous asphalt pavement under different temperature, different load and different kinds of asphalt was analyzed. The result shows that with saturated water rate increasing, the deormation of porous asphalt mixture increases and dynamic stability of rutting experiment decreases. For porous asphalt pavement under different kinds of asphalt, when saturate water rate is lower than 60% , the deormation increases rapidly with saturated water rate increasing. When saturafed water rate is morn than 60% , saturated water rate has small effect on deormation . With the higher temperature and the larger load, the more significantly the rutting resistance of porous asphalt pavement reduces.
