公路交通的噪声是影响沿线环境的不利因素,国外许多国家从本世纪六十年代末即开始进行研究,逐步采取了一些减小噪声的措施并获得一定的效果。本文对公路噪声的产生原因作了简要阐述后,介绍了一种减少噪声的路面——用透水地沥青铺筑的路面,文中对此种路面的构造、试验路的试验结果、施工注意事项作了简介。同时,还介绍有低噪声路面的四种排水方案。近年来,我国亦对路面噪声开始进行研究,本文所阐述的内容,对国内公路交通噪声的研究工作有现实的参考价值。
The noise of highway traffic is the unfavorable factor that affects the environment along the route. Many foreign countries started to study from the end of 1960s and gradually adopted some noise reduction measures and achieved some results. After the brief introduction of the causes of road noise, this paper introduces a noise reduction road surface - the pavement constructed by permeable asphalt pavement. The paper discusses the construction of the road surface, the test results of the test road, the construction precautions Brief introduction. At the same time, it also introduces four drainage schemes with low noise road surface. In recent years, our country also started to study on the road noise. The content of this article has a realistic reference value for the research on the domestic road traffic noise.
