随着国民经济的快速发展,我国道路里程增加、等级提高、路况改善,道路交通量也迅速增长,不可避免地给环境造成了不同程度的道路噪声污染。道路交通噪声主要由汽车发动机噪声、轮胎与地面的滚动噪声等组成,通过改善路面的结构组成和路表物理特征,可以减少轮胎和路面的滚动噪声。
With the rapid development of the national economy, the mileage of roads in our country has increased, the rank has been improved, the road conditions have been improved, and the volume of road traffic has also risen rapidly. This has inevitably caused various environmental noise pollution to the environment. Road traffic noise is mainly composed of automobile engine noise, rolling noise of tires and ground, etc. It can reduce the rolling noise of tires and pavement by improving the structural composition and physical characteristics of road surfaces.
