| Abstract: | Through the laboratory test of expansive soil with adding in lime,the change of viscous grain content,the characteristics of expansion and shrinkage,the Atterberg′s limits,the compaction and the shear strength are analyzed to get the optimal ratio of adding in lime,and that is pointed out that optimal ratio of adding in lime can be quickly gotten by the viscous grain content,the Atterberg′s limits and the free swell. |
