Wheel-Tracker
TBTACZ-HWT Hamburg wheel tracker is designed to evaluate the rutting resistance and moisture susceptibility of hot mix asphalt (HMA). The asphalt testing equipment measures permanent deformation under repeated moving load by recording rut depth and number of load cycles to failure. Test results can identify insufficient binder strength, weak aggregate structure, or moisture-induced damage. Specimens can be immersed in water at controlled temperature throughout the test to assess water sensitivity.
