Automatic CBR Test Machine

The UTS-0856.ACPR Automatic 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.

The UTS-0856.ACPR is composed of a robust and compact two column frame with adjustable upper crossbeam driven by an electromechanical  ram with a maximum capacity of 50 kN and a data acquisition and processing system.

The UTS-0856.ACPR 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. This main feature allows the user to perform tests complying to AS, BS, EN, ASTM or AASHTO standards with the same machine.

U-Touch PRO Control Unit

U-Touch PRO Control Unit is designed to control CBR test machine UTS-0856.ACPR to perform CBR tests meeting local standards.

The Unit can perform CBR tests as a stand-alone without the use of a PC or with the USOFT-0856 software and a PC. Control of machine, acquisition of load and displacement data in real time are provided by the unit.

Main Features

• Can test with displacement control
• Real time display of test graph.
• 4 analog channels for load cell and displacement sensors
• Calibration function for channels.
• Programmable digital gain adjustment for load-cell and potentiometric sensors, voltage and current transmitters
• Closed-loop PID for steady pace rate
• The digital unit saves the load value at user defined displacement values .
• The load corresponds to the displacements corrected respect to the linear region of the data has also saved
• The % CBR at 2.5 mm and % CBR at 5 mm is also automatically calculated and saved

The CBR Test Machine is supplied complete with;

• Load Cell, 50 kN
• Penetration Piston (UTS-0870)
• Linear potentiometric displacement transducer25 mm x 0.001 mm (UTGM-0062) with holder (UTM-0114)
• Computer Software
• LAN Connection Cable
