Skid resistance is an important property relating to the safety of highway surfacing materials. It has been researched for many years with many countries having national guidelines. Skid resistance is not a constant value but varies dependant on the age of the surface; the type, intensity and speed of trafficking and environmental conditions. Skid resistance is related to other surface properties such as noise and rolling resistance. The UK skidding policy has been place for the past 40 years and specifies an investigatory level of skid resistance dependant on risk. A number of devices are used in the UK to measure skid resistance. Road surfaces are measured using SCRIM, GripTester or the pendulum. In the laboratory skid resistance of the coarse aggregate is assessed using the PSV test with the Wehner Schulze and Road Test Machine devices currently being assessed to assess asphalt mixes. Much development has been carried out in the UK in recent years to better understand skid resistance. This has coincided with the development of smaller stone size, high stone content asphalt mixes such as proprietary thin surfacings.
