摘　　要：通过实体工程LSMA-13混合料的设计,介绍了该混合料配合比的设计方法,提出了通过绘制粗集料松装间隙率VCADRC、VCAmix与4.75mm筛孔通过率变化曲线确定粗集料用量的方法,能够为同类混合料的设计提供借鉴。By means of design of LSMA - 13 mixture for entity engineering, the paper introduces design procedures for present mixture proportioning, poses methods to determine consumption of coarse aggregate through drawing the changed curve of relaxation gap rates VCA DRC and VCA as well as rate of passing through 4.75mm sieve mesh, that are enabled to offer reference for design of similar mixture.

关 键 词：LSMA-13混合料 粗集料骨架间隙率 矿料间隙率
