摘　　要：基于矿料主骨料空隙体积填充法(CAVF)设计了3种不同空隙率的半柔性路面大空隙基体沥青混合料,采用马歇尔试验、透水试验与空隙率测定等试验评价其性能。结果表明,采用CAVF法设计的3种不同空隙率的基体沥青混合料,设计空隙率与实测空隙率较为接近,且具有适当的强度,较好的排水性能,砂浆的可灌入性强。In this paper,three kinds of large void basic asphalt mixture with different voidages for semi-flexible pavement are designed based on the coarse aggregate voids-filling method （CAVF）.The Marshall Test,permeability test,determination of voidage and other performance tests are presented.The results show that the designed voidge and measured voidge are close in the three kinds of basic-asphalt-mixture with different viodages designed by CAVF,and have the appropriate strength,good drainage performance,the mortar can be poured strong.
