Wheel-Tracker

Wheel-Tracker

It is mainly used for the determination of the high temperature anti-rutting ability of the asphalt mixture, and can also be used for the auxiliary inspection of the asphalt mixture ratio design.
It provides a lot of real and effective data for the domestic industry standard of the instrument prepared by the Ministry of Communications. Our institute is the main unit of the People's Republic of China Transportation Industry Standard rutting test machine.
