摘　　要：文中通过级配分析、击实试验,分析了高液限粘土路基填土的物理力学特性和压实特性。认为现行以压实度为指标的压实控制标准不完备,是引起公路病害的主要原因之一。建议引入空气体积率作为粘土路基压实程度的评判标准,并提高现有压实度控制标准中路堤的压实度。Through the study of particle size analysis and compaction test, this article analyzes the physical and mechanical properties and the compacting capability of filling soil for road-bed high liquid limit clay. As reason of the highway diseases that the criterion of compaction in existence is deficient. In volume ratio of air is used as an assistant criterion for the compaction of high liquid limit clay. a result, it is one important order to solve this problem, And, it is suggested that the degree of compaction for the road embankment should be improved.
