Abstract:

Appropriate winter road maintenance requires that road managers identify road sections where treatment is needed, and thermal mapping has been widely used for this. Thermal mapping develops a unique surface temperature pattern for each route (a gthermal fingerprinth) based on the fact that the pattern of road surface temperatures is reproducible under similar weather conditions. Another technique for clarifying road surface conditions involves determining the slipperiness of the road surface. Although the recent development of a practical device that allows continuous measurement of road surface friction has expanded the application of slip indicators in winter road maintenance, it is impossible to constantly measure changing road surface friction. If, like road surface temperature, the distribution of road surface friction is reproducible, road managers can reduce for road surface friction measurement. This study aims to verify the reproducibility of friction distribution (a gfriction maph) under snowy and snow-free conditions by using an expressway as a case study route. The friction distributions showed high reproducibility even in winter under similar conditions. The friction values derived from the friction fingerprints produced using friction data collected under snowy conditions were also found to show high reproducibility.
