STANDARDS: EN 12697-22 | AASHTO T-324
The Hamburg wheel tracking device can be used to determine the resistance of Hot Mix Asphalt (HMA) to rutting and moisture sensitivity.
Matest model “SmarTracker™” meets and exceeds EN and AASHTO.
It is intelligently designed with innovative features and the needs of the end users in mind.
The most versatile wheel tracker on the market has independent motors for each wheel which assure separate rutting analysis of each specimen.
Now you can perform wet or dry test with both wheels or run one wheel under dry and one wheel under wet condition simultaneously
during a single test.
Determine the creep slope, stripping inflection point and stripping slope with this state of the art and user friendly machine.
MATEST SmarTrackerTM has been developed by our R&D engineers and scientific in association with some of the most experienced and reputable
industry experts in the USA and the world.
Wheel load: 705 N
Wheel speed: from 20 to 30 cycles/minute.
EN 12697-22: 2500W heaters for air temperature control, ventilation
for temperature uniformity, probe for air temperature, all
controlled by the electronic system.
AASHTO T324: 4000W heaters, recirculating pump, automatic
feed and controls level.
Temperature control range: from ambient up to 75°± 1 °C
Table travel: 230 mm
Rut depth transducers range: 25 mm ± 0.1 mm accuracy.
Slab thickness: adjustable from 38 to 120 mm
Power supply: 220V 50-60Hz
Dimensions: 1400x1300x1300 mm
Weight: 450 kg approx.
No added stress to operators back from lifting
heavy wheel assemblies.
Sample holders slide into position and eliminate
demanding lifting and placement of samples into the
Hood keeps technicians away from moving parts
and provides better temperature control while the
test is being conducted.
