钢渣是炼钢过程中加入石灰、萤石等造渣溶剂而形成的复合固融体,由于化学成份和后期处理工艺的不同,钢渣的物化性能有着较大的差异,造成其难以大综量合理利用,大量的钢渣堆存造成了一些列环境污染及土地资源占用等问题。钢渣的道路化的应用一直是国内外研究者对钢渣综合利用的重要用途之一。本研究主要通过相关试验确定钢渣细集料与钢渣粉在面层SMA-13沥青混凝土中的应用可行性,对钢渣SMA-13混合料的级配设计、路用性能以及经济性进行了研究,解决目前钢渣在沥青混凝土中应用存在的安全风险和成本过高的问题。为后续钢渣在沥青混凝土中的应用提供技术保障。
Due to the difference of chemical composition and post-treatment process, the physical and chemical properties of steel slag are greatly different, which makes it difficult to achieve large comprehensive and reasonable Utilization, a large number of steel slag storage caused some of the column of environmental pollution and land resource use and other issues. The roadway application of steel slag has always been one of the important uses of steel slag at home and abroad. In this study, the feasibility of application of steel slag fine aggregate and steel slag powder in the surface of SMA-13 asphalt concrete was determined through relevant tests. The grading design, road performance and economy of steel slag SMA-13 mixture were studied. Solve the current steel slag in the application of asphalt concrete security risks and the cost of the problem. For the subsequent application of steel slag in asphalt concrete to provide technical support.
