This machine is used in laboratory, for evaluating the deformation (rut) depth of a bituminous mixture subjected to cycles of passes of a loaded rubber wheel under constant and controlled temperature conditions.
To perform the test, a wheel tracking apparatus is used to simulate the effect of traffic and to measure the deformation susceptibility of the bituminous sample.
Wheel tracker fully satisfies both EN 12697-22 and BS 598:110 specifications and may perform the test following both procedures A and B, clearly specified by the EN Standard.
Technical Specifications
