Wheel tracking is used to assess the resistance to rutting of asphaltic materials under conditions which simulate the effect of traffic. A loaded wheel tracks a sample under specified conditions of load, speed and temperature while the development of the rut is monitored continuously during the test. Test specimens can be either slabs prepared with a laboratory compactor or 200mm Ø cores cut from the highway.
The CRT-WTEN1 wheel tracker performs both procedures A and B specified for the small scale device in EN 12697-22. Procedure A requires that six specimens are tested. For procedure B only two specimens need to be tested, but rut depth must be measured at more points along the longitudinal rut profile. To speed up the testing process the CRT-WTEN2 was designed to test two specimens simultaneously.

  • Tests materials for roads with axle loads up to 13 tonnes
  • Rigid test frame built from extruded aluminium section
  • Integral temperature controlled cabinet with double glazed doors
  • PID control of test temperature in the range 40°C to 62°C
  • Rack for pre-test temperature conditioning of specimens
  • The CRT-WTEN2 tests two specimens simultaneously
  • Specimens compacted with the Cooper Technology Roller Compactor can be transferred directly to the wheel tracker without de-moulding
  • Closed-loop speed control
  • User-friendly Windows™ software
  • Supplied with certification of a UKAS accredited calibration
  • User friendly, intuitive and reliable Windows™ software developed using LabVIEW™
  • Software is designed to perform EN 12697-22 Small device
  • Software automatically starts the wheel tracker, maintaining the speed at the specified 26.5 cycles per minute
  • Measures rut depth and sample temperature automatically at regular intervals
  • The rut profile is captured automatically by the software and analysed to calculate the rut depth
  • A continuously updated on-screen graph shows rut depth versus time, along with the rut profile and temperature
  • Software stops the wheel tracker on completion of a test and prints a test report if required
  • Stored test data can be analysed and compared with other test data utilising a spreadsheet package
  • Utilities are included for transducer check, diagnostic routines and RTD calibration
