日前在北京三环路的改造中 ,北京市首次在劲松路段铺筑大空隙透水率低噪音沥青路面。该技术能有效地排除路表积水 ,使雨天行车时路面与车轮稳定接触 ,减少雨天交通事故 ,经北京市环保局等专业检测机构的检测 ,能有效降低噪声 4dB。近年来 ,由于道路等级不断提高 ,路面性能得到
Recently, in the transformation of the Third Ring Road in Beijing, Beijing Municipality laid the large void permeability low-noise asphalt pavement for the first time in Jinsong section. The technology can effectively exclude the water from the road surface, make the road surface stable contact with the wheel when driving in rainy days, and reduce traffic accidents in rainy days. The detection by the professional testing organizations such as Beijing Municipal Environmental Protection Bureau can effectively reduce the noise by 4dB. In recent years, due to the continuous improvement of the road level, the pavement performance has been obtained
