Wheel tracking is used to assess the resistance to rutting of asphaltic materials under conditions which simulate the effect of traffic. In this machine, two 500 x 180mm specimens are tested simultaneously by tracking with wheels fitted with pneumatic tyres under specified conditions of load, speed and temperature while the development of the rut profile is monitored at specified intervals during the test.The moulded specimens are inserted and removed from the wheel tracker using an Easy-load system.
A unique instrumented measurement device, linked to the data acquisition, is used to measure the development of rutting during testing. The test procedure and conditions are controlled and data acquired using Windows™ software running on a host computer via a high speed digital interface and signal conditioning system.

  • Tests materials for roads with axle loads of at least 13 tonnes
  • Unique rut profile measurement device linked to data acquisition system
  • Integral temperature controlled cabinet
  • Test temperature range 40 to 60°C
  • Tests for specified number of cycles or to specified rut depth
  • Double glazed doors for viewing test
  • Easy-load system for specimen handling
  • Conditioning of specimens at test temperature
  • User friendly Windows™ software
  • Automatic test start/stop
  • Closed loop speed control
  • Specimens can be compacted in the CRT-RCENLD-II and then wheel tracked without demoulding
  • 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 Large device
  • Integrated acquisition system for data capture and machine control
  • Software automatically starts the wheel motion and brings the specimens up into contact with the moving wheels
  • Rut depth of both specimens is monitored according to the procedure specified in the standard
  • Three linear displacement transducers are housed in a frame which slides over the moulds on each side of the machine
  • The frame is positioned at five pre-determined measurement points to allow a total of 15 rut readings to be automatically captured by the software
  • Readings are automatically stored and on-screen graphs show rut development as well as historical rut data. The acquired rut data is also saved to disk
  • Software stops the wheel tracker on completion of a test and prints a test report if required
  • The 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
