| 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．

| Abstract: | 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. |
