摘　　要：以山西省忻州市三大板块旅游公路偏关县境内第一期工程沿线4个标段弃渣为研究对象,从风化程度判定、弃渣母岩工程特性、风化岩集料工程特性3个方面进行资源特性分析,并以《公路路面基层施工技术细则》实施手册中规定的技术要求为判定标准,对其路面基层用可行性进行评价。试验结果表明:工程沿线弃渣母岩和破碎集料,工程特性参数指标基本符合路面(底)基层用规范要求,其破碎后混合料级配经优化调整后满足级配曲线要求,可以应用于二级及二级以下公路(底)基层。Focusing on the waste slag in four sections along the first-phase engineering of Three Major Tourist Highways in Pianguan County,Xinzhou City,Shanxi Province,this paper analyzed the resource characteristics from three aspects of weathering degree determination,engineering characteristics of the mother rock of the waste slag,and engineering characteristics of weathered rock aggregates.Regarding the technical requirements from the implementation handbook Technical Guidelines for Construction of Highway Roadbase as the criteria for determination,the feasibility of using the waste slag as the roadbase was evaluated.The test results showed that for the mother rock of waste slag and crushed aggregates along the engineering,the parameter indexes of engineering characteristics met the specification requirements of the use as the roadbase(subbase);the optimized gradation of the crushed mixture could meet the requirements of the gradation curve,and it could be applied to the secondary or below highway roadbase(subbase).
