Abstract

Pavement skid resistance, affecting wet-road accidents, deteriorates over time because of material properties, laying conditions, weather/seasonal effects and traffic. Skid resistance deterioration models are critical for design, maintenance and rehabilitation purposes, but very few of them explored the influence of traffic in terms of vehicle type and travel mode. This paper shows how it is possible to better model skid resistance deterioration by evaluating cumulated frictional dissipated energy in the tire footprint area. Full-scale accelerated pavement wear tests have been performed and analysed through an energy-based approach. Preliminary results seem promising for redefining the effect of traffic in deterioration models.
