| 摘 要： | 首先对不同细集料用量与ＳＭＡ混合料物理指标的关系进行了试验研究，然后通过变化级配的ＳＭＡ混合料的马歇尔试验，利用诺谟图来分析粗集料间隙率对ＳＭＡ混合料物理性状的影响；并通过车辙试验分析不同粗集料间隙率对ＳＭＡ混合料力学特性的影响。结果表明，粗集料间隙率是评价ＳＭＡ配合比设计的重要指标。

| Abstract: | In this paper,the tests were done firstly to study the voluminal character of SMA mixture with the variety to fine aggregate component;the relationship between VCA (the voids in the coarse aggregate)and physical characteristics of SMA,according to the Marshall Test on the different gradation SMA mixtures was analysised by means of nomogram.The change in the SMA mechanilal characteristics with Various VCA It was proved that VCA gets animportant role in the design of SMA composites |
