摘　　要：利用不同饱水率的车辙试验,对大空隙排水路面OGFC-13混合料在不同温度、不同荷载、不同沥青种类条件下进行水作用下的抗车辙性能分析.结果表明:随着饱水率的增加,变形量增大、动稳定度减小;对不同沥青的排水路面,当饱水率小于60%时,随饱水率增加变形量增加较快,当超过60%,饱水率对车辙变形量影响很小;温度越高荷载越大,水导致大空隙排水路面的抗车辙性能显著降越.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.
