The California Bearing Ratio or CBR test is used for the laboratory evaluation of the bearing value of highway sub-bases and sub-grade. The CBR is composed by a robust and compact two-column frame with adjustable upper cross beam driven by an electromechanical ram with a maximum capacity of 50 kN and a data acquisition and processing system. The CBR is designed to load the penetration piston into the soil sample at a constant rate to measure the applied load and piston penetration at pre-determined intervals.

The ram speed can be set between 0.5mm/min to 5mm/min by using Digital Readout Unit. This main feature allows user to perform tests complying to BS / EN or ASTM standards with the same machine. Rapid adjustment of the platen is also provided.
