The Digital 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 driven by an electromechanical ram with a maximum capacity of 50 kN and a data acquisition and processing system.
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 cell ﬁtted to the upper cross beam to read stability values and the 25 x 0.01 mm Displacement Sensor ﬁtted to the column.
Supplied complete with LCD Control Unit, 50 kN capacity Load Cell, 25 x 0.01 mm Displacement Sensor and CBR Penetration Piston.
