摘要
大孔隙结构的排水性沥青路面可以及时排除路表水,提升雨天行车安全性。对当前排水性沥青路面抗滑性能测试方法存在问题进行分析,提出采用现场刹车距离试验评定其刹车性能,并结合实际工程的行车能见度、道路安全事故发生率等来评定排水性沥青路面的行车安全性。测试结果表明:排水性沥青路面可以有效缩短刹车距离,提高雨天行车的能见度,降低道路的交通事故率,具有良好的安全性能。
The drainage asphalt pavement with macropore structure can timely eliminate the water on the surface of pavement,so as to improve the traveling safety in rainy day. The analysis on issues existed in anti- slide performance test method of the current drainage asphalt pavement is made,and the assessment on its braking performance is put forward by adopting site braking distance test. And in combination with the travelling visibility of practice project,road safety accident rate and so on,the assessment on the travelling safety of drainage asphalt pavement is made. The test results show that： the drainage asphalt pavement can effectively shorten the braking distance,improve the visibility of travelling in rainy day,and reduce the traffic accident rate of road,thus having good safety performance.
