摘要:
通过对公路交通噪声特征,低噪声路面的特点、结构、降噪机理及国内外研究现状的分析,对宁杭高速二期工程低噪声路面与普通路面噪声监测结果进行对比分析,确认低噪声沥青路面具有比较明显的降噪效果,路肩处噪声可降低3~4dB(A),路外15m处可降低1.1~3.5dB(A).

Study on the Noise Reduction Effect by Monitoring the Low-noise Pavement
Abstract:
By analyzing the characteristics of the road traffic noise, the feature, the structure and the noise reduction mechanism of the low-noise pavement, the research results of traffic noise and comparing monitoring results of the low-noise pavement of the second phase of the Ning(bo)—Hang(zhou) highway and the traditional pavement, the low-noise asphalt pavement has a better effect than the traditional pavement in traffic noise reduction. Compared to the traditional pavement, the traffic noise level of the low-noise asphalt pavement is 3~4 dB (A) lower in the embankment, and 1.1~3.5 dB (A) lower in the position of 15 meters away from the road.
