摘　　要：该文分析了集料性状、级配组成、压实功与VMA的关系;探讨了最小VMA的意义及其标准的发展过 程;查清了旋转压实法和马氏击实法造成VMA不同的内因,建议推广旋转压实法。In this paper the relationship of aggregate shape, aggregate grading, compaction function and VMA was analyzed. The meaning of minimum VMA and the development process of its criterion were also discussed. The internal relations of the different experimental values of VMA caused by Marshell and cyratory compacting were explained.The cyratory compacting was recommended.
