摘要
本文在沥青路面降噪机理和技术要求的基础上,指出轮胎/路面噪声的测试方法,并对LNAP13降噪沥青路面的应用情况进行测试分析。试验测试结果表明,相比密级配沥青混合料,大空隙的LNAP13降噪幅度达到2~3d BA,可在一定情况下替代声屏障,具有良好的经济效益。
Based on the asphalt pavement noise reduction mechanism and technical requirements, this paper pointedout the testing methods of stated tire/road noise, tested and analyzed the application LNAP13 noise reduction asphaltpavement. Experimental results show that, compared with dense-graded asphalt mixture, LNAP13 pavement with alarge gap can reduce the noise by 2- 3 d BA, and can replace the sound barrier in certain circumstances with goodeconomic returns.
