CBR Test Machine is designed for performing laboratory evaluation of the CBR value of highway sub-bases and sub-grade and determination of the strength of cohesive materials.

The device is composed of a robust and compact two column frame with adjustable upper cross beam.

The CBR Test Machine designed to load the penetration piston into the soil sample at a constant rate to measure the applied load and piston penetration at predetermined intervals.

The frame has 50 kN capacity. Two test speeds are provided 1.0 mm/min for BS and 1.27 mm/min. for ASTM/EN/AASHTO Tests.

Loading and unloading are down from the front panel by UP/DOWN buttons.

For safety, the up and down travel of the lower platen is limited the use of limit switches.

The measuring system consists of a 50 kN capacity Load Ring fitted to the upper cross beam to read stability values and the 30 x 0.01 mm Analog Dial Indicator fitted to the column.

Supplied complete with 50 kN Load Ring with 0,01 mm resolution Analog Dial gauge, 30 x 0,01 mm Analog Dial Indicator and CBR Penetration Piston.
