摘　　要：以扬州市生活垃圾焚烧发电厂的炉渣为研究对象,进行了筛分、含水率、击实、CBR、烧失量等公路土工试验,试验结果表明:垃圾炉渣的颗粒组成特征为公路土分类中的粗粒土,属于级配良好砾土,最大干密度1.524g·cm-3,最佳含水率为16%,液限为40.4%,塑性指数25.9,CBR值为5.4,有机质含量3.36%,适合作为二级及以下等级公路的路基填料。The slag produced by the household refuse incineration power plant in Yangzhou was taken as the study object, and soil tests on screening, moisture content, compaction, CBR and loss on ignition were conducted. The results show that the slag is graded as gravel soil with good gradation consisting of coarse grain soil; the maximum dry density is 1. 524 g · cm^-3, optimal moisture content is 16%, liquid limit is 40.4%, plasticity index is 25.9, CBR value is 5.4, organic content is 3.36 %, which make it suitable for secondary highway and below as subgrade fill.
