Portable skid resistance pavement friction tester

The pendulum instrument is a power pendulum impact type instrument. It is based on the basic principle that “the energy loss of the pendulum is equal to the work done when the rubber piece at the end of the swing arm slides across the road surface and overcomes the friction of the road surface”.

The BM-III pendulum instrument has all the functions of the BM-II pendulum instrument, and can also be used as the coarse aggregate buffing value test in JTG E42-2005 (the type II pendulum meter does not have this function).

The pendulum friction coefficient tester (referred to as pendulum instrument) is an instrument for measuring the friction coefficient of road surface, airport runway, marking paint.

It is also possible to pass the measurement of the typical road friction coefficient as one of the basis for determining the formulation of the seed-preserving tire.

The instrument is easy to debug and easy to operate. It has less impact on traffic during testing, and the data is stable, and can be used indoors and outdoors.
