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 standard 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 BM580 consists of:
- Electrically driven loaded wheel arms
- Temperature controlled water bath
- Highly accurate rut measurement system
- Windows based software
