modle BM-III Skid resistance and friction tester Skid Resistance friction testing machine Skid Resistance Friction Tester Pendulum Skid Tester pendulum instrument coefficient of friction pendulum tester pendulum instrument Pendulum friction coefficient tester It is a kind of determination of pavement, airport runway, marking paint and so on friction coefficient of the instrument. Product Description: 1. Used to test skid resistance on existing road surfaces, 2. Consisting of a pendulum arm, rotating about a spindle attached to a vertical pillar and mounted on a trianglar base with adjustable feeet. This method provides a measure of the skid resistance properties of a surface either in the field or in the laboratory. This method measures the skid resistance of a small area of a surface (approximately 0.01 m2) and this should be considered when deciding its applicability to a pavement surface which may have variable surface characteristics, e. G. Block paving. This apparatus is used for the skid resistance measurement of asphalt pavement and concrete pavement, in order to evaluate the skid resistance of pavement in moist condition. Technical parameter: 1.Put the weight:1500g 2.Place the center of gravity of:410mm 3.Rubber piece of pavement is static pressure:22.2N 4.The end from the place of the rubber feet:508mm 5.On the road surface sliding length:126mm
