The track test is used to determine the susceptibility of hot asphalt mixtures (HMA) to deformation under a constant load applied by a wheel with repeated passes with continuous groove measurement and a fixed temperature. Two versions available as prescribed by EN 12697-22 Small size device: sample conditioning in air and/or water. Both versions can be upgraded with the automatic system that lifts one of the wheels of the sample that has reached the groove target, continuing the test on the other sample.
