Skid Resistance

Civil Tech provides Pavement Skid Resistance which has been recognizes as the most important parameter in reducing traffic accidents especially in wet conditions. The knowledge of the friction coefficient and skid resistance is valuable information for safety enhancement of roads.

British Pendulum Tester is used to measure the frictional resistance of road at sections which appear to be potentially slippery and unsafe against skidding.

The Portable Skid Resistance Tester (PSRT) is based on the Izod principle. In operation, a pendulum of a known mass rotates about a vertical spindle. The head of the pendulum is fitted with a Rubber Slider, which has a specific hardness and resilience. When released from a horizontal position, the pendulum head strikes the sample surface with a constant velocity. The distance travelled by the pendulum after striking the sample, is determined by the friction resistance of the sample surface. The skid resistance values which approximately correspond to the coefficient of friction times 100 are read directly from the clearly engraved scale. 

• The scope is to measure the frictional resistance of road at sections which appear to be potentially slippery and unsafe against skidding.
• Skid resistance is an important pavement evaluation parameter because inadequate skid resistance will lead to higher incidences of skid related accidents.
• Skid resistance measurements can be used to evaluate various types of materials and construction practices.
• Skid resistance depends on a pavement surface’s microtexture and macrotexture.
