上海逸仙高架NovaChip~超薄磨耗层降噪效果实测与分析

随着国家环境保护政策的完善,道路噪声日益成为环境保护工作及沿线居民关注的重点。道路工作者也在不断致力于低噪音沥青路面材料的研究。NovaChip 沥青路面是一种超薄粘结磨耗层,它采用间断级配,通过大空隙率达到防滑降噪的作用。介绍了NovaChip的材料特性及其降噪机理,实测了NovaChip 试验路段的路面噪音并同其他路段进行比较,结果表明,NovaChip的降噪效果明显。并且,由于其施工方便,可以在很短时间内开放交通,在城市薄层罩面中具有很好的应用前景。

Measuring and Analyzing of Noise-Reducing effect for NovaChip very-thin-friction-layer on Yixian overhead way,Shanghai.

As the progressing of environmental policy, dwells along the road and environment-protectors have giving their focus on traffic noise gradually. At the same time, road engineers are devoted to researching of low-noise asphalt pavements. NovaChip asphalt is one of the very-thin-friction-layers, which is gap-graded. It achieves noise-deducing and skid-proof effect through its porous characteristic. The material characteristic and noise-deducing principium of NovaChip is introduced in this article, and the noise of the experimental road is also measured and compared with common road. The result shows that NovaChip pavement has a obvious noise-deducing effect. What＇s more, the traffic can be opened in a short time due to facility in constructing NovaChip ~ pavement. As a result, it has a extraordinary prospect among the thin-friction-layers for urban using.
