The C.B.R. value usually is selected at 2.5 mm penetration. If the C.B.R. at 5 mm is greater than at 2.5 mm, the test should be repeated. If the check test results are similar, then the value for 5 mm penetration is used as. Generally, the CBR test is conducted for three test specimens and the average value is taken of the three.
