摘　　要：钢渣、粉煤灰排放量大、利用率低,利用钢渣粉煤灰做路面基层材料可大量利用工业废渣,减少天然石料的开采,是一种生态建筑材料。主要研究了钢渣粉煤灰的路用性能,其中主要包括配合比、无侧限抗压强度、劈裂抗拉强度、回弹模量等常用性能,通过试验比较证明了钢渣与粉煤灰组合完全可以做道路基层,供施工技术人员借鉴。Steel slag and fly ash, as a kind of industrial waste and ecological building material, can be used as road base material to reduce the exploitation of natural stone. The performances of steel slag and fly ash ad- mixture in pavement are studied, mainly including the mixing ratio, unconfined compressive strength, split ten- sile strength, resilient modulus and other commonly used performances. It is proved through experimental com- parison that the admixture of steel slag and fly ash is acceptable to be used as road pavement base course.
