摘　　要：通过级配分析、击实试验,分析了含砂低液限粉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的不完备,是引起公路病害的主要原因之一。为了解决这一问题,引入空气体积率作为粉土压实的辅助控制标准,并建议提高现行路堤的压实度控制标准。Through the study of grading analysis and compacting test, this article analyzes the physical and mechanical property and the compacting capability of silt. As a result, it is one of the important reasons for the highway damage that the criterion of compaction in existence is deficient. In order to solve this problem, volume ratio of air is used as an assistant criterion for the compaction of silt. And, it is suggested that the degree of compaction for the road embankment should be improved.
