  • 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 LBM585 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.

Standards

  • EN 12697-22 Small device, AST 01:2004, BS 598-110:1998

Features

  • Test 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 of 40ºC to 62ºC
  • Rack for pre-test temperature conditioning of specimens
  • The CRT-WTEN2 tests two specimens simultaneously
  • Specimens compacted with a compatible 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

Software

  • User friendly, intuitive and reliable Windows™ software
  • 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
  • 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 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

The LBM585 Wheel Tracker consists of:

  1. A solid extruded aluminium frame supporting an insulated cabinet which uses PID control linked to a PRT for accurate closed loop temperature control
  2. A rubber-tyred wheel runs on top of the specimen and applies 700 or 52M to the specimen
  3. A table which is reciprocated a distance of 230mm on linear bearings at 26.5rpm.
  4. One LVDT for rut measurement
  5. Large double-glazed doors for full access which enable visual monitoring of the test if required
