The California Bearing Ratio (CBR) field test yields in–situ strength of soils and some base course materials. The field procedure uses a loading jack to force a piston into the soil, noting the piston load and depth of penetration. The jack is loaded against dead weights or a heavy piece of equipment such as a loaded dump truck. Gilson CBR equipment can be ordered as complete sets or separately as individual components.
Components of Gilson's Field CBR Equipment are ordered individually for tests performed according to ASTM or Army Corps of Engineers (C.O.E.) methods. Select an ASTM or C.O.E. Jack, English or metric Penetration Dial Gauge, Load Rings, and other components required. Additional surcharge masses may be needed to simulate large pavement loads.
