摘要
路面噪声不仅会产生声污染,还会破坏路面,处理路面噪声成为当前急需解决的社会问题。文章通过剖析沥青混凝土路面因为材质和振动所产生的噪声,提出交通运行监控措施,优化橡胶沥青路面结构类型、橡胶粉掺量,以及橡胶沥青混凝土路面施工工艺流程,降低交通噪声对人类生活造成的影响。实验结果表明,优化交通运行车速,选取大粒径密级配混凝土,采用橡胶沥青混凝土施工路面,噪声明显下降,路面噪声得到了有效控制,策略具有可行性。
Road noise will not only produce sound pollution,but also destroy the road,Dealing with road noise has become an urgent social problem.By analyzing the noise caused by material and vibration of asphalt concrete pavement,this paper puts forward traffic operation monitoring measures,optimizes the structure type of rubber asphalt pavement,the amount of rubber powder,and the construction process of rubber asphalt concrete pavement,so as to reduce the impact of traffic noise on human life.The experimental results show that the road noise is obviously reduced and effectively controlled by optimizing the traffic speed,selecting large particle size dense graded concrete and using rubber asphalt concrete to construct the road.The strategy is feasible.
