摘要
该文阐述了,针对道路实际运营中存在的问题,结合路面路用性能的要求,对排水性沥青路面设计所进行的研究。采用混合料最大公称粒径13.2 mm的试样,通过室内试验对排水性沥青混合料的降噪、抗滑及排水性能分别进行测试。试验结果表明各项性能均远远优于普通沥青混合料。接着,重点分析了空隙率对性能的影响,并通过理论计算验证了排水性沥青路面在道路中应用的可行性。最后兼顾路面耐久性能的要求,综合探讨了排水性沥青路面设计中的各项关键技术。
The article sets forth the problems existing in the practical operation of road, and studies the design of porous asphalt pavement according to the requirements of pavement performance. The noise reduction, slip resistance and drainage performance of porous asphalt mixture are separately tested by using the maximum nominal size 13.2-mm sample of mixture and through the indoor test. The test result shows that its various performances are all greatly excelled the common asphalt mixtures. The article focuses analysis on the influence of voidage on the performances, validates the application feasibility of porous asphalt pavement in the roads through the theoretical calculation, and comprehensively discusses various key technologies in the design of porous asphalt pavement by taking account of pavement durability performance.
