  • This is a dual arm immersion wheel tracker is widely used to evaluate the resistance to rutting and moisture susceptibility of asphalt mixtures following either EN12697-22 or AASHTO-T324.
  • Specimens can be prepared in the laboratory, or cores taken from the road can be used.
  • Loaded steel or rubber wheels track a sample under regulated load, speed and temperature, whilst the development of the rut is constantly monitored and recorded throughout the test.

Features:

  • Able to perform AASHTO-T324 and EN 12697-22
  • State of the art software which provides higher level users with options, and lab technicians ease of use
  • A dedicated immersion wheel tracker (Wet and dry wheel trackers compromise on temperature control)
  • A mechanical re-circulating water bath controls the temperature to within ± 0.5°C in a range of (20-75) ºC
  • Variable speed range between 15 and 30RPM
  • Two displacement transducers attached to the wheel support arms measure the depth of the ruts as they develop with a resolution of 0.01mm to a maximum rut depth of 50mm
  • The depth of the rut is measured automatically and constantly as specified in the AASHTO and EN standards
  • Rubber or stainless-steel wheels, and various widths to alter the applied pressure
  • Various mould options including laboratory compacted and cores (AASHTO and EN)
  • UKAS Certificate supplied

Uses:

  • Investigation of resistance to rutting
  • Investigation of moisture susceptibility
  • Testing of laboratory compacted slabs
  • Testing of field cores
  • Production of creep slope, stripping inflection point and stripping slope

Software:

  • User friendly, intuitive and reliable Windows™ software developed using LabVIEW™
  • Software allows two standards but fully customisable testing methods AASHTO-T324 and EN 12697-22
  • The operator is guided through every step of the test
  • Real-time display of current water temperature, specimen temperature and rut depth
  • Data is recorded to disk at regular intervals for further analysis
  • Software communicates with the Immersion wheel tracker via the USB interface
  • Utilities are included for transducer check, diagnostic routines and calibration
  • Excel import data output

The Immersion Wheel Tracker LBM580 consists of:

  1. Electrically driven loaded wheel arms
  2. Temperature controlled water bath
  3. Highly accurate rut measurement system
