【摘要】：钢渣是一种工业副产品,常被当成废弃物而随意处理,但其具有耐磨、抗滑、高碱性等特征,与沥青间粘附性较好,可以作为集料使用。研究了钢渣原材料性能、钢渣透水沥青混合料设计、路用性能。研究表明:钢渣具有耐磨、抗滑、高碱性等特征;钢渣透水沥青混凝土配合比设计时,倾向于采用钢渣粗集料与天然细集料复配的方案,并采用SBS改性沥青和纤维稳定剂增强其稳定性和耐久性;利用钢渣制备透水沥青混凝土具有良好的高温稳定性、优异的水稳定性,钢渣透水路面渗水和抗滑性能完全满足规范要求。该研究推动了钢渣透水沥青混凝土的发展,促进了钢渣在道路建设中的广泛应用。
[Abstract]:Steel slag is a kind of industrial by-product, which is often treated as waste at will, but it has the characteristics of wear resistance, skid resistance, high alkalinity and good adhesion with asphalt, so it can be used as aggregate. The raw material performance of steel slag, the design of steel slag permeable asphalt mixture and the road performance were studied. The results show that steel slag has the characteristics of wear resistance, skid resistance and high alkalinity. In the mix proportion design of steel slag permeable asphalt concrete, it tends to adopt the combination scheme of steel slag coarse aggregate and natural fine aggregate, and SBS modified asphalt and fiber stabilizer are used to enhance its stability and durability. The preparation of permeable asphalt concrete from steel slag has good high temperature stability and excellent water stability. The seepage and skid resistance of steel slag permeable pavement fully meet the requirements of the code. This study promotes the development of steel slag permeable asphalt concrete and promotes the wide application of steel slag in road construction.
