摘　　要：为评价级配变化对沥青混合料结构组成特性的影响,以体积参数为研究对象,采用旋转压实方式成型沥青混合料,并对其展开后续试验。计算空隙率、间隙率、饱和度等体积参数,并得出各体积指标的单因素方差分析结果。统计分析结果表明:级配的变化对混合料的各项体积指标均有显著影响,其中以粗集料间隙率(VCA)变化幅度最大。In order to evaluate the effect of gradation variation on the structural characteristics of asphalt mixture, the volume parameters were chosen as the research object, and the sample of asphalt mixture was prepared by rotary compaction for subsequent tests. The volume parameters such as porosity, voids in aggregate and saturation were calculated, and the results of one-way analysis of variance of each parameter were obtained. The change of gradation has a significant effect on the volume indicators of the asphalt mixture, among which voids in coarse aggregate （VCA） shows the largest change.
