How do you convert bearing capacity to CBR value?

To convert bearing capacity to California Bearing Ratio (CBR) value, you can use empirical relationships or correlations established through field and laboratory testing. A common method is to apply the formula: CBR = (q / P) × 100, where ( q ) is the bearing capacity (in kPa) and ( P ) is the pressure corresponding to a CBR of 100 (typically around 2000 kPa for standard tests). It’s important to note that this conversion can vary based on soil type and conditions, so local calibration may be necessary for accurate results.
