California Bearing Ratio Test Simplified



Due to the large volume of soil sample material and effort involved, the conventional California bearing ratio (CBR) tests are laborious and time consuming. Hence, an attempt was made to use the Proctor mold itself with a proportionately smaller plunger to estimate the CBR values. The good agreement between the CBR values obtained using the conventional mold and plunger and the Proctor mold and a smaller plunger (with a correction factor) suggests the feasibility of this approach, especially for fine-grained soils. The recommended minitest apparatus and procedure make the CBR test much simpler.
