OVERVIEW

The results of these tests are used with the curves to determine the thickness of the pavement and its component layers. This is the most widely used method for the design of flexible pavement.

SPECIFICATIONS

The California Bearing Ratio test, (usually called CBR test) is an empirical test developed in California, the USA for determining the Relative Bearing Ratio and expansion characteristics under known surcharge weight of the base, sub-base and subgrade soils for the design of roads, pavements, and runways.

FEATURES

The CBR test is used extensively in the selection of materials and control of subgrades. The test can be performed in the laboratory on prepared samples or in-situ on location. It is important to appreciate that this test, being of an empirical in nature, is valid only for the application for which it was developed i.e., the design of highway base thickness.
