It is used for a test that directly measures the load required to penetrate the soil to determine the magnitude of bearing capacity and evaluates the bearing capacity characteristics relatively based on the ratio to a standard load.
This test is used to directly measure the load required to penetrate the soil at the site to determine the magnitude of the bearing capacity, and to relatively evaluate the bearing capacity characteristics based on the ratio to a standard load. The field CBR test directly measures the load necessary to penetrate a standard-sized loading piston into the soil, reflecting the current magnitude of the bearing capacity of the subgrade or base course at the site, and evaluates the bearing capacity characteristics relatively based on the ratio to a standard load.
