Guide to Asset Management Part 5F contains guidelines for and background notes on the collection of skid resistance data for road network management purposes in Australia and New Zealand. The guide should be viewed in parallel with the Austroads Guide Management of Road Surface Skid Resistance. Skid resistance is a condition parameter that characterises the contribution that a road surface makes to the level of friction available at the contact patch between a road surface and vehicle tyre during acceleration, braking and cornering manoeuvres. Research undertaken in a number of countries is consistent in indicating that a disproportionately high number of crashes occur on road surfaces that have a low level of skid resistance and/or low surface texture. In mitigation, equipment and test methods have been developed to allow the measurement of skid resistance (the particular domain of this guide) and surface texture, with strategies and policies also being developed for the analysis and use of the data collected in the management of skid resistance at either an individual site or network level.
