摘要
文章利用旋转压实仪(SGC)进行旋转压实试验,借助压实特性的四个参数,分析了沥青混合料在施工和使用过程中的压实特性。结果表明:沥青混合料压实特性的主要影响因素是集料级配和沥青用量,粗型级配沥青混合料的抗变形能力未必高于细型级配沥青混合料。
After conducting the experiment by SGC,the article analyzes the compaction characteristic of bituminous mixture found during the construction and using process based on its four parameters.The result shows that the compaction characteristic of bituminous mixture is mostly influenced by aggregate grading and the usage amount of asphalt.The non-deformability of AC-C grading bituminous mixture may not be higher than that of AC-F grading.
