摘要
为了合理利用四川石棉县开采石棉所产生的大量废弃物石棉尾矿,将石棉尾矿作为粗集料应用于沥青混合料中,结合高速公路沥青路面建设,用图解法分析计算出石棉尾矿作为粗集料的配合比,并得出合成级配曲线满足规范要求的级配范围内,说明石棉尾矿应用于沥青路面配合比是可行的.
To use reasonably the asbestos debris in Shimian county, Sichuan province, asbestos debris is studied so that it can be used in asphact mixtures as a coarse aggregate. Considering the highway asphalt pavement construction, graphic method is used to analyze and calculate the gradation of the asbestos debris as a coarse aggregate, and synthetical gradation curve is abtained to meet gradation range standard. It indicates that asbestos debris can be used in asphalt pavement gradation.
