摘要
OGFC型降噪路面是在普通的沥青砼或水泥砼路面上铺筑一层大孔隙的沥青混合料。这种大孔隙能有效的降低车辆的行驶噪声,并在雨天可以减少水雾的产生,增大路面的抗滑性能,保证了行车的安全舒适。本文介绍了OGFC型降噪路面的技术特点、在我国的应用现状及发展前景。
OGFC reducing noise pavement is constructed by laying a layer of big eyelet asphalt admixtures on the ordinary asphalt or concrete pavement surface. This pavement can reduce vehicle noise, bring down vehicle spray in rainy day, and enhance anti-slide performance to ensure driving safety. This paper introduced the technical characteristics, current situation and developing trend of OGFC pavement in China.
