    May 14, 2013· California bearing ratio = (P T /P S)x100. Where. P T = Corrected unit (or total) test load corresponding to the chosen penetration curve, and. P S = Unit(or total) standard load for the same depth of penetration as for P S taken from standard code. Report. The CBR values are usually calculated for penetration of 2.5 mm and 5 mm.


    Report the CBR value to the nearest second decimal. Take the average of three test specimens as the CBR value of the test. Generally, the CBR value at 2.50mm penetration will be greater than that at 5.00mm penetration and in such case take the value at 2.50mm as the CBR value.
