Automatic CBR Test Machine (UTS-0856.ACPR)

SKU UTS-0856.ACPR Categories ,

Compacted Road Base and Subbase Soils

Code UTS-0856.ACPR
Standards EN 13286-47; BS 1377:4; ASTM D1883; AASHTO T193; NF P94-078; AS 1289.6.1.1; UNI CNR 10009


  • 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 (3/4”).
  • 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 BS, EN, ASTM or AASHTO standards with the same machine.
  • Rapid adjustment of the platen is also provided by up and down buttons which are located on the front panel of the machine.
  • The UTS-0856.ACPR is supplied complete with a 50 kN load cell, penetration piston, linear potentiometric displacement transducer (25 mm x 0.001 mm).
U-Touch PRO Control Unit:
  • U-Touch PRO Control Unit is designed to control CBR test machine UTS-0856ACPR to perform acc. to EN, ASTM/AASHTO and BS 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
  • The control unit has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seamless manner to activate the option or enter a numeric value to set the test parameters and see all the data while the test running.
  • Control Unit offers many addition unique features.
  • You can save test results in its internal memory and can be controlled remotely from anywhere around the world.
Main Features:
  • Can make the test with displacement control
  • Real time display of test graph.
  • 4 analogue channels for load cell and displacement sensors
  • Can control second frame
  • 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
  • Calculates corrected CBR value at 2.5 and 5 mm the digital unit saves the load value at user defined displacement values such as 0.625, 1.25, 1.875, 2.5, 3.75, 5, 7.5,10, 12.5 mm
  • 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.
USOFT-0856 UTEST Software for CBR Test:
  • USOFT-0856 CBR Test Software is developed for EN/ASTM/AASHTO/BS CBR Test. The software includes control of machine, acquisition of load and displacement data, generating and saving reports.
  • The software prepares a summary result for the user that will only need some specific loads such as at 0.625 mm, 1.25 mm, 2.5 mm and 5 mm.
  • The software continuously updates load, stress and displacement till the end of test.
  • Software can automatically draw the best tangent line and perform the upward concave correction as suggested by ASTM D 1883.
  • The corrected stress values are then calculated respect to this offset.
  • The CBR value at 2.5mm and 5.0mm are calculated by using the standard load values at those penetrations.
  • On the general information tab, by entering necessary information, dry density calculations can be made through the software.
  • The software supports metric, SI and Imperial unit system.

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
Dimensions 480x650x1150 mm
Weight (approx.) 110 kg
