The CBR is the ratio of the bearing load that penetrates a material to a specific depth compared with the load giving the same penetration into crushed stone. The test measures neither Stiffness Modulus nor Shear Strength directly, but gives a combined measure of both. [2] Penetration is measured by applying the bearing load on the sample using a standard plunger of diameter 50 …
