WebCBR test is a penetration test, wherein a standard piston is used to penetrate the soil at a standard rate of 1.25 mm/minute. California Bearing Ratio value is defined as the ratio of load per unit area required to penetrate a soil mass by a standard plunger at a specified rate to that corresponding load required to penetrate standard material.
