摘要
通过对路面噪声来源和降噪机理的分析,提出从改变路面结构和材料类型的角度来消减和吸收噪声,并在南京绕城公路高桥门高架路段采用LNAP13降噪路面,实际测试LNAP13沥青路面的降噪效果。
Through analysis on noise source of road and noise reduction mechanism,the method of reducing noise from the aspects of changing the pavement structure and material type has been proposed. And LNAP13 noise reduction pavement has been applied at Nanjing Ring Road Gaoqiaomen Elevated Road Section to test the noise reduction performance of LNAP13 asphalt pavement in a practical way.
