Abstract

Seasonal variations in skid resistance have been a recurring phenomenon that has been studied by many researchers. The impact of seasonal variations will vary across geographic regions, due to different amounts of rainfall. During the summer months, especially during prolonged dry periods, small rock chips on the surface continuously become fine-grained particles as vehicles move and act as a polishing agent. During long rains (winter months), fine matter disappears and the heavier and more coarse sand acts as a polishing agent, resulting in slippery resistance to surface texture. Increases the coarseness. Many variables affect the measurement of skid resistance. It is not yet possible to fully investigate the possible influence of various factors affecting the seasonal variations in skid resistance. Precise measurement of seasonal variation in skid resistance is a relatively complex task. This paper introduces and investigates various methods of seasonal slip resistance correction available in the world and evaluates their feasibility of usage in Iran.
