日本对低噪声路面的研究始于80年代末。这比欧洲国家晚了大约十年。本文对低噪声路面的研究进行了历史的、分类的梳理。当以致密沥青路面为控制路面时，排水性沥青路面和多孔弹性路面被识别为低噪音路面。（1）通过对所有论文的初步降噪效果和降噪效果衰减的估算，得出排水性沥青路面的降噪性能在3-5 dB（A）之间，年衰减量约为1 dB（A）/年。(2)通过对性能恢复的总结，合理解释了清洗机只能恢复排水效果，不能恢复降噪性能。(3)多孔弹性路面的降噪性能得到了很大的改善。这也让我们期待多孔弹性路面将从根本上解决日本城市地区的公路噪声问题。
The research on low noise pavement in Japan started at the end of 80's. It was about ten years later than that of European countries. This paper historically and categorically included the researches concerning low noise pavement. When considering dense asphalt pavement as control pavement, the drainage asphalt pavement and porous elastic road surface are identified as low noise pavement. The author summarized the results of all the papers and acquired the following conclusions : (1) The result of the rough estimation through all the papers concerning initial noise reduction effect and the effect degradation indicates the amount of the performance of drainage asphalt pavement might be 3-5 dB (A) and the annual degradation is about 1 dB (A)/year. (2) The summary of the paper concerning the performance recovery gave us the reasonable explanation that the cleaning machine is only available to recovering the water drain effect but not to restore the noise reduction performance. (3) Porous elastic road surface showed the great improvement in the noise reduction performance. It also lets us expect that porous elastic road surface will give the fundamental solution to the highway noise problem in urban areas of Japan.
