Larger Image
California Bearing Ratio (CBR) apparatus, developed from specifications of the California State Highway Department, the laboratory apparatus used in this method determines the bearing ratio of soil when it is compacted and tested in the laboratory by comparing the penetration load of the soil to that of a standard material. The method covers the evaluation of the relative quality of subgrade soils, but is applicable to subbase and some base course materials. Meets ASTM D1883; AASHTO T193.
