CALIFORNIA BEARING RATIO TEST
OBJECTIVE
To determine the California bearing ratio by conducting a load penetration test in the laboratory.
NEED AND SCOPE
The california bearing ratio test is penetration test meant for the evaluation of subgrade strength of roads and pavements. The results obtained by these tests are used with the empirical curves to determine the thickness of pavement and its component layers. This is the most widely used method for the design of flexible pavement.
This instruction sheet covers the laboratory method for the determination of C.B.R. of undisturbed and remoulded /compacted soil specimens, both in soaked as well as unsoaked state.
enclosed find herewith the detailed test report format for sampling and testing
