A measuring instrument used to give a continuous trace of surface friction whilst travelling at highway speeds.
Water delivery systems are custom designed depending on your vehicle and testing distance requirements.
Using the Side Force principle as described in ASTM E670 and AASHTO T268 this device uses two ASTM E1551 tyre's mounted at a fixed angle to the direction of travel. This side force is measured by a load measuring device which directly computes the tyre surface frictional properties.
Optional Global Positional System (Pave®GPS) linked to Friction Data can be supplied at a resolution to sub 1 meter accuracy. System calibration can be performed by the operator with the purchase of the Calibration Matt and Trolley. A Precision Tyre Pressure Gauge can also be supplied to monitor for correct tyre pressures.
