文章分析了交通噪声产生的机理,探讨了降低沥青混凝土路面噪声的途径,分析了国内外路面噪声测试方法,结合国外经验,采用国内测试方法对同步薄层罩面与原有路面进行了交通噪声测试,对同步薄层罩面降噪机理进行分析,结果表明,同步薄层罩面可以有效减少行车产生的交通噪声。 This paper analyzes the mechanism of traffic noise, discusses ways to reduce the noise of asphalt concrete pavement, analyzes the domestic and international road noise test methods, combined with foreign experience, using domestic test methods for simultaneous thin layer overlay with the original road traffic noise The results show that the synchronous thin-layer overlay can effectively reduce the traffic noise caused by driving.
