Abstract

This paper firstly discusses infrastructure asset management goals and the development in New Zealand (NZ) of the NZdTIMS system of predictive deterioration modeling. The paper then demonstrates that measured skid resistance varies significantly from month to month, week to week and even day to day, based on a number of external variables. The outcome being that it is very difficult to develop credible incremental deterministic prediction models for skid resistance. The paper then reports upon research that is currently being undertaken at the University of Auckland, New Zealand into the variability of road pavement skid resistance over time. The methodology includes the measuring and analyses of skid resistance with rainfall and contaminants in the field using the GripTester, SCRIM and the Dynamic Friction Tester (DFTester) and secondly by means of controlled laboratory experiments on prepared samples. The research demonstrates the importance of understanding the significance of a single skid measurement as a ‘snapshot’ in time.
