The CBR is obtained as the ratio of the unit stress required of effect a certain depth of penetration of the piston (1935 mm) into a compacted specimen of crushed aggregate/soil at some water content and density to the standard unit stress required to obtain the same depth of penetration on a standard sample of crushed stone. Thus. CBR = Test
