| Abstract: | Through the experimental research on amelioration of expansive soil with mixing in clime-flyash,the characteristics of expansive and shrinkage and the changes of compressive strength are analyzed to get the optimal ratio of adding in clime-flyash for amelioration of expansive soil.The result show that the optimal ratio of adding in clime and flyash is 8% and 5%.which can provide the reference for treatment of expansive soil roadbed. |
