California Bearing Ratio [CBR] Test Machines

CBR Test Machine with Load Ring – UTS-0852The California Bearing Ratio (CBR) test is a measure of the strength of subgrade soil and highway sub base and subgrade via a penetration test. It is designed for testing cohesive materials with a particle size less than 19mm.

Laboratory Machines

CBR Test Machine with Load Ring – UTS-0852

This machine includes a load ring and dial gauge and is used to measure force and piston travel. Two travel speeds 1mm/min & 1.27mm/min. 50 kN capacity

CBR Test Machine with Digital Readout – UTS-0854

This machine includes digital force and a travel readout. Two travel speeds 1mm/min & 1.27mm/min. 50 kN capacity.

Automatic CBR Test Machine – UTS-0860Automatic CBR Test Machine – UTS-0860

  • Variable ram speed between 0.5-5 mm/min. Compatible with data acquisition and testing software.
  • System will record corrected CBR values at 0.625 1.25 1.875 2.5 3.75 5 7.5 10 12.5 mm, along with the %CBR at 2.5 and 5 mm
  • Displacement or load control
  • Live test Graph display
  • 50 kN capacity
  • Excel output

Field Testing Systems – UTS-0865Field Testing Systems – UTS-0865

Onsite evaluation of base and sub base is achievable due to field CBR testing. Sites un-disturbed by construction activity are most preferred when performing the field test. It is also possible to saturate test sites to collect conservative data.  

It is also possible to assemble the machine with conversion frame UTS-0867 to create a mechanical CBR test machine.
