摘要
本文通过变化级配的SMA混合料的马歇尔试验研究 ,利用诺谟图来分析粗集料间隙率对SWA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。
According to Marshall Test on varied gradations of SMA (stone mastic asphalt) mixture, the relationship between the VCA (voids in the coarse aggregate) and physical properties of SMA is analyzed with the nomogram, and the relationship between VCA and the mechanical properties of SMA is also studies through the rutting test. It is proved that VCA is an important factor in assessment of SMA mixture ratio design.
