随着汽车数量的增加,行车安全问题逐渐引起社会各界的重视,如何提高沥青路面雨天抗滑性能成为当前研究的重点。文中根据国内外研究状况,设计了一种大孔隙环保沥青混合料ESM-13;对沥青路面抗滑指标进行研究,对环保安全型沥青路面进行室内抗滑试验,并对采集到的抗滑数据进行分析。结果表明正常工况下SMA混合料的抗滑性能强于ESM混合料,但ESM混合料在雨天工况具有很好的抗滑性能和排水能力。
With the increase of the number of cars, the issue of traffic safety has gradually attracted the attention of all walks of life. How to improve the anti-skid performance of asphalt pavement rainy days has become the focus of current research. In this paper, according to the research situation at home and abroad, a macroporous green asphalt mixture ESM-13 was designed. The anti-skid index of asphalt pavement was studied. The indoor safety test of asphalt pavement was carried out. Analyze. The results show that under normal conditions SMA mixture skid resistance is stronger than the ESM mixture, but ESM mixture in rainy conditions with good skid resistance and drainage capacity.
