This test method determines the California Bearing Ratio (CBR) of soils in place by measuring penetration load. The CBR evaluates the quality of subgrade, subbase, and some base course materials. The test procedure involves soaking a soil sample, applying a standard load via a plunger to the sample at a controlled rate, and measuring penetration to determine the CBR value as a percentage of standard loads. Two CBR values are obtained from the 2.5mm and 5.0mm penetration depths and the higher value is report
