The California bearing ratio (CBR) is a very commonly used laboratory test for predicting the strength of subgrade layer. The aim of this study is predicting the strength of the subgrade soil from fine grained soils. The findings obtained from test results are Atterberg limit, grain size, compaction, and free swell tests. The California bearing ratios were conducted to find out the strength parameters, and correlated with liquid limit, plastic limit, plastic index, maximum dry density and optimum moisture content. The CBR values were determined in the laboratory are compared with the predicted values.
