摘　　要：以G109线惠农至黄渠桥段改扩建工程为例,将钢渣应用于铺筑上面层和基层,路面整体铺筑效果良好。分析了钢渣作为筑路材料适用性;结合具体的工程设计,从预处理、配合比以及施工等方面做了具体要求。钢渣应用于公路工程中,不仅能减少大宗固废的存量,减少污染,也能节约大量传统筑路材料,有利于公路建设绿色低碳化发展。Taking the reconstruction and extension project of Huinong to Huangquqiao section of G109 line as an example,the steel slag is applied to the paving of the upper layer and the base layer,and the overall pavement paving effect is good.The applicability of steel slag as road construction material is analyzed.Combined with specific engineering design,specific requirements are made from the aspects of pretreatment,mix ratio and construction.The application of steel slag in highway engineering can not only reduce the stock of bulk solid waste,reduce pollution,but also save a lot of traditional road construction materials,which is conducive to the green and low-carbon development of highway construction.
