摘　　要：以SAC级配理论和SMA骨架判断标准为基础,从混合料骨架密实结构角度分析了粗集料含量、撑持料含量及空隙率三个因子对混合料的高温稳定性的影响.结果表明:撑持料的含量对混合料的骨架结构及压实性能都有较大影响,混合料的骨架密实度与其高温稳定性呈抛物线关系.Based on the SAC gradation theory and SMA skeleton judge standard, from the angle of the mixture skeleton＇s dense situation, the influences of three factors induding the coarse, separating aggregate contents and void mixture on the high temperature stability peformance are analyzed. Result shows that the content of separating part of the aggregate has strong effect both on the mixture＇s skeleton construction and on the compaction performance, and on the mixture＇s skeleton and dense degree are relevant to the high temperature stability performance in a kind of parabola rule.

关 键 词：级配 骨架密实结构 高温稳定性
