HIGHWAY SLIP FRICTION TESTER (HFT) 6875H - 1

Dynatest 6875H HIGHWAY SLIP FRICTION TESTER (HFT) The Dynatest 6875H Highway Friction Tester is designed for maintenance testing to evaluate changes in highway pavement friction characteristics due to weathering, polishing, aging, and contaminants. It can be used in difficult test areas, such as bridge decks, off-ramps, city streets, and intersections, giving an accurate continuous friction for the erea being tested. The Highway Friction Tester is a fully instrumented vehicle that uses a Dynatest Two Axis Force Transducer mounted on a retractable fifth wheel assembly.
