Abstract

In this paper, we studied mechanics characteristic of whole weathered granite improved soil. We analysesed its changes of fluid plasticity index before and after improvement in different compaction condition. We improved the full weathering granite by adding different proportion of lime and cement. We analysised the changes of liquid limit and plastic limit of improved soil in the different mixed ratio condition and we got the conclusion that the improved soil plasticity index decreased with lime or cement dosage increases, also changed over time. Improved soil liquid limit, plastic limit and plasticity index changed with the addition of lime, cement dosage changes exponentially.
