公路存在一定程度的安全隐患和环境污染。排水防滑沥青路面在于缩短刹车距离,提高行车安全性。通过采用排水防滑沥青面层,面层结构由现有的密实结构变为骨架结构,高分子橡胶改性沥青胶结料,保证路面足够大孔隙率时,具有足够的稳定度和高低温性能,提高路面粗糙度,足够纹理深度,保持路面良好的抗滑性能和排水性能。应用实体工程现场检测,排水防滑沥青面层可缩短刹车距离15%以上,有效避免交通事故的发生。
Highway there is a certain degree of security risks and environmental pollution. Drainage non-slip asphalt pavement is to shorten the braking distance, improve traffic safety. Through the use of drainage anti-skid asphalt surface layer, surface structure from the existing compact structure into a skeleton structure, polymer rubber modified asphalt binder to ensure that the road has a large enough porosity, with sufficient stability and high temperature performance, improve Pavement roughness, enough texture depth, to maintain the road surface slipperiness and drainage performance. Application of physical engineering on-site testing, drainage skid asphalt surface can shorten the braking distance of more than 15%, effectively prevent traffic accidents.
