California Bearing Ratio Test: CBR Values & Why They Matter
Penetrations vs. load values are plotted on a graph and corrected following the procedure specified in the test standard. Corrected stress values from penetration depths of 0.100 and 0.200in (2.54 and 5.08mm) are divided by standard stresses of 1,000psi (6.9mPa) and 1,500psi (10.3mPa), then multiplied by 100. In most cases, CBR values decrease ...
