摘　　要：在沥青混合料配合比设计过程中,细集料毛体积相对密度对于空隙率、矿料间隙率等相关体积指标的计算有直接影响。文章通过JTG E42-2005中关于细集料坍落度法试验,探讨了细集料饱和面干状态的确定及级配变化对细集料毛体积相对密度及吸水率的影响。The fine aggregate bulk specific gravity and the water-absorbency have the material effect on the ratio design of bituminous mixture.This paper initially searches the fine aggregate close saturated-surface-dry condition and gradation for fine aggregate density and the water-absorbency through the experimental method of fine aggregate density and water-absorbency in JTG E42-2005.
