Wheel Tracking Test

A cored or laboratory compacted slab of hot mix asphalt is subjected to repeated passes of a loaded wheel while the resultant rut depth is monitored. Wheel tracking is popular because it is more simulative than other laboratory methods of assessing resistance to permanent deformation and results have been shown to correlate well with in-service pavement rutting. There are two widely used wheel tracking test methods in Europe: one was developed at LCPC in France and the other is based upon the method developed at the TRL in the United Kingdom. Less widely used, the Hamburg wheel tracker tests specimens submerged in water and provides a measure of durability as well as resistance to rutting. There is no national standard for wheel tracking in the United States.
