钢渣是炼钢的副产品,通常作为废弃物处置,但其棱角分明,具备耐磨性高、抗滑性好的优点,是替代天然集料的优质筑路材料.检测分析防城港市某钢铁厂转炉热闷钢渣的化学成分及物理力学性质,按照0、20%、40%、60%、80%、100%六组比例等体积替换同规格辉绿岩,制备不同钢渣掺量的RAC-13C沥青混凝土,研究钢渣掺量对其路用性能的影响.依托南宁吴圩至上思高速公路项目,铺设钢渣沥青混凝土上面层试验段,检测其现场路用性能.结果表明,掺入钢渣的沥青混凝土具备更为优异的高温稳定性和抗滑性.将钢渣掺入沥青混凝土中,是缓解优质筑路材料资源不足、减少环境污染的有效举措.
Study on Application and Performance of Green Steel Slag Asphalt Concrete in Expressways
Steel slag,a by-product of steelmaking,is typically treated as waste,yet it has distinct advantages,including angularity,high wear resistance,and excellent skid resistance,making it a suitable substitute for natural aggregates in road construction.The chemical composition and physical-mechanical properties of converter steel slag from a Fangchenggang steel plant are analyzed.Diabase of the same specification is replaced in equal volumes at ratios of 0%,20%,40%,60%,80%,and 100%to produce RAC-13C asphalt concrete with varying steel slag contents,and the impact on road performance is evaluated.In the Nanning Wuxu to Shangsi Expressway project,a test section of steel slag asphalt concrete surface layer is laid,and its in-situ performance is assessed.Results indicate that steel slag asphalt concrete exhibits superior high-temperature stability and skid resistance.Incorporating steel slag in asphalt concrete effectively addresses the shortage of high-quality road materials and reduces environmental pollution.
