California Bearing Ratio of Fine Grained Soil and its Correlation

A series of laboratory California Bearing Ratio (CBR) tests and laboratory compaction tests have been performed to study the CBR value for both unsoaked and soaked condition of fine grained soil and also compaction characteristics of the fine grained soil. Six types of fine grained soil have been used in the present investigation. From the experimental results, it has been found that average degree of saturation of fine grained soil at optimum points (OMC and MDD) are around 81%. With the increase in compaction energy, the CBR values for both unsoaked and soaked condition increases when sample prepared at OMC of respective compaction energy. To estimate the unsoaked CBR and soaked CBR of fine grained soil nonlinear power model has been developed.
