Early-Life, Long-Term, and Seasonal Variations in Skid Resistance in Flexible and Rigid Pavements

Skidding contributes to up to 35% of wet weather accidents. Increased temperature and surface wear and polishing may affect the available friction and further increase skid-related accidents. Several studies have attempted to examine and quantify these variations mostly with inadequate or inappropriate conclusions. The surface friction of both port-land cement concrete (PCC) and asphalt concrete (AC) pavements was measured monthly to determine …
