b336a53425 Tests are carried out on natural or compacted soils in water soaked or un-soaked conditions and the results so obtained are compared with the curves of standard test to have an idea of the soil strength of the subgrade soil. Apply the load and note the penetration load values. Weight of mould compacted specimen. 2. Test Procedure & Steps 4. C B R Apparatus Used 3. C.B.R Definition 2. Uses, Applications & Significance 1.

The results obtained by these tests are used with the empirical curves to determine the thickness of pavement and its component layers. The California Bearing Ratio Test (CBR Test) is a penetration test developed by California State Highway Department (U.S.A.) for evaluating the bearing capacity of subgrade soil for design of flexible pavement.

Take other samples and apply different blows and repeat the whole process. USES AND SIGNIFICANCE of California Bearing Ratio Test: The CBR test is one of the most commonly used methods to evaluate the strength of a sub grade soil, sub base, and base course material for design of thickness for highways and airfield pavement. Then place the specimen under the penetration piston and place surcharge load of 10lb. Test Data Observations & Calculations 5. Back to top .
