The CS-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 CS-WTEN2 was designed to test two specimens simultaneously.

  • Tests materials for roads with axle loads up to 13 tonnes (28.5klb)
  • 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 (104°F) to 62°C (143°F)
  • Rack for pre-test temperature conditioning of specimens
  • The CS-WTEN2 tests two specimens simultaneously
  • Specimens compacted with the Cox & Sons Roller Compactor can be transferred directly to the wheel tracker without de-molding
  • Closed-loop speed control
