摘要
排水降噪音路面是一种新颖的沥青路面,它由于具有20%的空隙率,因而具有良好的排水降噪音功能。课题组在广东铺筑排水路面的实践中,进行了室内、外的研究,取得了一定的经验,对今后在广东铺筑排水路面有一定的参考价值。
Permeable noise - reducing pavement is a new kind of asphalt pavement. It exhibits favorable permeability and noice- reducing functions due to the porosity of 20%. In this paper, design method on mixing ratio of permeable pavement is presented, applying asphalt and aggregate which are commonly used in the pavement construction in Guangdong Province. And the experimental studies are carried at the same time. This study provides important guidance on the design and construction of permeable pavement.
