Skid resistance performance profiles

Managing skid resistance is an essential part of Queensland Department of Transport and Main Roads (TMR) responsibilities to ensure traffic safety. TMR released its skid resistance management plan as a central strategy for managing skid resistance. In managing skid resistance on Queensland state-controlled road networks, a Road Analyser and Recorder device had been used in monitoring skid resistance. TMR endeavours to provide proactive approaches in managing skid resistance. However, it is extremely difficult to predict skid resistance deterioration rates in future so that skid resistance treatments could be planned ahead. With the availability of skid resistance data at the network level, TMR wishes to make use of these data to find ways to predict skid resistance performance in future. A cooperative research project was established between TMR and the Australian Asphalt Pavement Association (AAPA) to analyse these skid resistance data and to develop skid resistance performance profiles (i.e. skid resistance deterioration rates) for its road network. Skid resistance data collected between 2004 and 2007 were used in the analysis. This paper presents a proposed methodology employed in developing skid resistance performance profiles.
