Pendulum Friction Skid Resistance Tester
The Pendulum Skid Tester measures the frictional resistance between a rubber slider mounted on the end of a pendulum arm and the test surface. This provides highway engineers with a routine method of checking the resistance of wet and dry surfaces to slipping and skidding, both in the lab and on site.
It is based on the Izod principle: a pendulum rotates about a spindle attached to a vertical pillar. At the end of the tubular arm a head of known mass is fitted with a rubber slider.
The pendulum is released from a horizontal position so that it strikes the sample surface with a constant velocity. The distance travelled by the head after striking the sample is determined by the friction of the sample surface.
This instrument is used to measure the skid resistance of asphalt pavement marking, stone or other materials (specimen), to evaluate the skid resistance of pavement and pavement material (specimen) in wet condition.
