两种沥青混合料的级配与VMA关系分析

Study on Relation of VMA and Gradation of Two Asphalt Mixtures

研究发现,不同混合料可能有不同的性能中心级配,对沥青路面混合料离析程度的控制,采用统一的通过率变化值的限制方法并不一定合适。同时沥青混合料级配通过率的相同变化,会给不同设计级配的混合料性能带来不同程度的改变。

Studies indicate that different asphalt mixtures have different central gradations connected with asphalt mixture performance. It is not suitable to apply the uniform percent passing value as the limit method for segregation control of asphalt mixture. Meanwhile, the same changes of percent passing will make different change in asphalt mixture performance.
