CBR Component Sets

CBR Component Sets are available with analog or digital components designed for quick installation on Load Frames and most other manufacturers. The components feature sophisticated instrumentation required to measure load and penetration for California Bearing Ratio (CBR) Tests. Each component in the set can be easily installed on the Load Frames with included fixtures.

Digital Set includes a Two-Channel Data Readout, 10,000lbf (44.5kN) Load Cell, 2in (50.8mm) Linear Variable Displacement Transducer (LVDT) with a holder, and the CBR/LBR Penetration Piston. Gilson's Data Acquisition Software can be purchased separately to obtain real-time testing data, calculations, and prepares reports in accordance with ASTM and AASHTO requirements.

Note: The Data Acquisition Software can only be used with digital component sets.

Analog Set includes a 6,000lbf (26.7kN) or 10,000lbf (44.5kN) capacity Load Ring, CBR/LBR Penetration Piston, and a 1x0.001in Dial Indicator with a holder for displacement readings The Load Ring is machined from a high-strength aluminum alloy plate for repeatable compression measurements and is supplied with a calibration graph.
