彩色OGFC沥青混凝土在透水路面铺装中的应用
|
摘要
透水路面铺装能通过较大的空隙迅速排除路表降水,减小路表水膜厚度,使行车时车轮与路面有足够的接触面积,从而避免高速行车时产生的水漂现象,并能大大减少因飞溅产生的水雾,提高路面抗滑性及行车安全性,此外,彩色OGFC沥青混凝土具有丰富的色彩,能够满足城市道路功能化建设的要求。通过彩色透水沥青混合料组成设计、施工工艺控制两方面,对彩色透水路面铺装技术在实际工程中的应用进行了介绍,为其他工程提供经验。
Permeable paving can quickly eliminate road surface precipitation through large gaps and reduce the surface water film thickness,so that the wheels and the road surface have enough contact area during driving,thus avoiding the phenomenon of water drift caused by high-speed driving,and can greatly it reduces the water mist generated by splashing,improves the skid resistance of the road surface and the safety of driving. In addition,the color OGFC asphalt concrete has rich colors and can meet the requirements of the functional construction of urban roads. In this paper,the application of color pervious paving technology in actual engineering is introduced through the design of color pervious asphalt mixture and the control of construction process. It provides experience for other projects.
