回收废料用于沥青道路铺筑的研究与展望

道路铺筑和养护要消耗大量的集料和矿粉,回收料的替代使用有助于保护节约天然资源。结合沥青混合料和集料的各种路用指标,对各类可用作沥青道路铺筑的回收废料进行研究,其中包括钢渣、玻璃、塑料、橡胶、水泥、陶瓷等工业、建筑废料以及生活垃圾焚烧灰等。根据回收料的颗粒大小、硬度、粗糙度、孔隙率、弹性等特性,将它们分别用于道路各个层面结构中,其体现出与天然集料和矿粉相同甚至更优越的路用性能。

Research and Prospect of Application of Recycled Wastes in Pavement of Asphalt Road

Pavement and maintenance of roads should consume a good deal of aggregates and mineral powders, and alternative use of recycled materials assists in protecting and saving natural resources. In combination with various road indices of asphalt mixtures and aggregates, this paper studies all types of recycled wastes used for pavement of asphalt roads, including industrial and construction wastes such as steel slag, glass, plastic, rubber, cement and ceramic, etc. as well as incineration ash of domestic garbag according to their characteristics of grain size, hardness, roughness, porosity and elasticity, etc. cled wastes are applied in various bedding surface structures of roads respectively and embody road performance as natural aggregates and mineral powders and even more excellent. e, etc. In the recy- the same
