California Bearing Test, CBR Test, California Bearing

California Bearing Ratio (CBR) - The ratio of the force per unit area required to penetrate a soil mass with a circular plunger of 50 mm diameter at the rate of 1.25 mm/ min to that required for corresponding penetration of a standard material. The ratio is usually determined for penetrations of 2.5 and 5 mm.

What is the California Bearing Ratio (CBR)? - Definition

The California bearing ratio (CBR) test is a penetration test used to evaluate the potential strength of subgrade, subbase, and base course material including recycled materials. The results are used for the design of roads and airfield pavements. The test was first developed by the California State Highway Department.

California bearing ratio typical values | CBR Testing UK

California bearing ratio typical values. What are the typical CBR values? The harder the material, the higher the CBR value. A CBR value of 2% is usually found for clay, high-quality sub-base will have CBR values between 80% and 100%, and some sands may have values around 10%.

California Bearing Ratio(CBR Test) of Subgrade Soil

The California Bearing Ratio Test(CBR test) is a penetration test that can be performed in the laboratory or in-situ. They can be considered as small scale bearing tests in which the ratio of penetration to the size of the loaded area is much greater than in bearing tests.

California Bearing Ratio - Pavement Interactive

The California Bearing Ratio (CBR) test is a simple strength test that compares the bearing capacity of a material with that of a well-graded crushed stone (thus, a high quality crushed stone material should have a CBR @ 100%).It is primarily intended for, but not limited to, evaluating the strength of cohesive materials having maximum particle sizes less than 19 mm (0.75 in.) (AASHTO, 2000{{1}}).

California Bearing Ratio (CBR), Plate Load Test (PLT

design stage. The California Bearing Ratio (CBR) test is commonly used to determine the suitability of a soil as a subgrade or subbase for highway and runway design and construction. Field plate load test is commonly used to pre-dict the deformations and failure characteristics of the soil/subgrade and modulus of subgrade reaction (k. s).
