A CBR value of 10-15% is generally considered good for soil in terms of its strength and bearing capacity. Higher CBR values indicate better soil strength and load-bearing capacity, which is important for road construction and other engineering purposes.

The California Bearing Ratio (CBR) test measures the strength of subgrade soil and its ability to support traffic loads in road construction and pavement design. By comparing the soil's resistance to that of a standard crushed rock material, the CBR test helps engineers evaluate the suitability of the soil for construction projects. A higher CBR value indicates better load-bearing capacity, guiding decisions on material selection and pavement thickness. Ultimately, this test ensures the durability and stability of roadways and infrastructure.
to test soil in its worst state
The link between CBR and bearing capacity if you get figures in CBR how can you link them to the bearing capacity in kPa, this is the link in soil testing.

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.
