Road surface friction: measurement, testing and accuracy

State road authorities act as the asset managers for their respective state road networks and it is their responsibility to maintain the road networks at a suitable operational level, thereby managing the risk on behalf of the respective governments. This responsibility translates to the public who are the main road users in a private or business capacity. Road roughness, texture, cracking, pavement strength etc. in Transport SA have been monitored and addressed for many years. Road surface friction is emerging as an issue in need of attention. The funds of road agencies are not limitless and making regular full network surveys is not always possible. A prioritising system is therefore a necessity in order to select test sites. Technical handling of this responsibility follows these steps: 1. Acquisition of measuring and associated test equipment; 2. Development of test and operational procedures; 3. Staff training; 4.Testing, accuracy and accreditation; 5. Selection strategies for network testing; 6. Policies. This paper will focus primarily upon the technical issues of handling this responsibility. (a) For the covering entry of this conference, please see ITRD abstract no. E212865.
