摘要
碎石骨架是 SMA混合料的标志 ,研究表明 ,粗集料间隙率 VCADRC与粗集料相对用量有关 ,细集料用量对混合料的骨架间隙率 VCAmix和性能有显著影响 ,细料过多 ,将会发生“干涉”,使骨架减弱。
The skeleton of crushed stone is marker about SMA mixture.The clearance percentage (VCA DRC ) depends on relative content of coarse aggregate.The fine aggregate content has significant influence on the clearance percentage (VCA mix ) and performance of SMA mixture.If fine stuff is more,interference will occur and the skeleton of crushed stone will be softening.
