摘要
通过采用相同级配组成、不同材料类型以及相同材料类型、不同级配组成等4种沥青混合料,分别使用马歇尔击实成型和Superpave旋转压实成型制备混合料,测试混合料的各项体积参数。试验结果表明:采用两种不同成型方式得到的混合料,在相同的油石比条件下,矿料间隙率之间、空隙率之间以及其他体积参数之间,不具备明显的相关性。
Four asphalt mixtures composed of the same gradations and the different material types,and the different gradations and the same material type are molded separately by Marshall Compaction mode and Superpave gyration compaction mode to test various volume parameters of the mixtures.The experimental result shows that the mixtures molded by two different molding modes have no obvious pertinences between the void rates and the porosity rates of mineral aggregates,and the other volume parameters under the same condition of the asphalt and aggregate ratio.
