دستگاه Double wheel tracker  

The wheel tracking test is used for determining the susceptibility of Hot Mix

Asphalt (HMA) to deformation under load by measuring the rut depth formed by

repeated passes of a loaded wheel at a fixed temperature.

The two methods according AASHTO T324 and EN 12697-22 are practically identical

except for:

- Test environment: Dry and wet for EN; wet for AASHTO

- Wheel material and size: rubber wheel, 203x50 mm (diameter x width) for EN;

steel wheel, 203x47 mm (diameter x width) for AASHTO

CONTROLS offer three models which satisfy all the above requirements.
