Continuous friction tester TPCFT-2

It is a trailer mounted device that is connected to a suitable tow vehicle and is able to measure the coefficient of friction of the pavement surface through continuous friction trace and side force measurement to reduce the risk of road accidents.
It consists of a measuring trailer, an electronic control device, a laptop and software. The trailer type measuring equipment moves forward under the towing of the tow vehicle. Through the skidding of the test wheels with special non-treaded tires at a certain angle, the sideway force perpendicular to the driving direction is generated. High-precision sensors measure and transmit the measured data to computer software for processing, and ultimately provide users with tables and curves of pavement surface position and friction coefficient. The measurement is controlled by computer software and the water output is automatically adjusted according to the driving speed so that the water film thickness between the test wheel and the road surface is 0.05~1 mm.
