摘要
排水性沥青路面采用大空隙开级配沥青混合料,具有良好的排水性能、抗滑性能、降噪效果等特点。排水性沥青路面使用性能的发挥受路面结构类型、路面材料、交通因素、气候因素等影响,需要采用合理的方法对其使用性能进行测试。重点分析了排水性沥青路面长期使用过程中的渗水性能、抗滑性能、交通噪声的变化情况。测试结果表明,排水性沥青路面各车道路面渗水均会有一个先增大后减少的过程,路面抗滑性能也存在先增加后减少的规律,而路面的减噪效果则随着时间的推移逐渐下降,并逐渐保持平稳趋势。
Drainage asphalt pavement adopted large gap open gradation asphalt mixture with features of good drainage performance, anti -slide performance and noise reduction effect. Performance of drainage asphalt pavement was influenced by pavement structure type, pavement materials, traffic factor, climatic factor and so on which required reasonable performance testing method. This paper mainly analyzed the water seepage performance, anti - slide performance and variation of traffic noise of drainage asphalt pavement during its long - term service. The testing results showed that water seepage of each lane of drainage asphalt pavement was fisrt increase and then decrease and so was the anti - slide performance. The noise reduction effect would decrease in course of time and gradually maintain steady.
