Main features
General description

The Digital Computerized 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 which have maximum particle sizes less than 19 mm (3/4”).

The machine is 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 machine has a digital read- out unit on its front panel connected to 50 kN load cell, linear potentiometric displacement transducer (25 mm x 0.001 mm), computer software and connection cable.

The Digital Graphic Display Data Acquisition and Control Unit is designed to control the machine and processing of data from load-cells, pressure transducers or displacement transducers which are fitted to the machine.

All the operations are controlled from the front panel touch screen. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seem less manner.

The Digital Graphic display is able to draw real-time “Load vs. Time”, “Load vs. Displacement” or “Stress vs. Time” graphics.

The digital computerized CBR Test Machine is supplied with:

Digital Touch Screen
Load Cell, 50 kN
Penetration Piston
Linear Potentiometric Displacement Transducer
Computer Software
Connection Cable
