California Bearing Ratio
The purpose of California Bearing Ratio test (CBR) was to provide an assessment of the relative stability of fine crushed rock base materials. This test is used exclusively in conjunction with pavement design methods. In view of the fact that early pavement design methods were based on soil classification tests rather than CBR values, it seems a reasonable assumption that CBR values are related to soil classification in some way. However, CBR values depend not only on soil type but also on density, moisture content and method of preparation. These factors must be taken into account when considering correlations between CBR and soil classification tests. Since the CBR value of a soil is also a measure of its performance as a subgrade, logic suggests that there should be some general relationship between the soil groups and CBR values, and several such correlations do exist.
