EXPERIMENTS WITH UNSALTED ROADS DURING THE WINTER 1982/83. EFFECTS ON ROAD CONDITIONS AND CONSEQUENCES FOR ROAD USERS AND ROAD MAINTENANCE AUTHORITIES

Försök med osaltade vägar vintern 1982/83. Inverkan på väglaget och konsekvenser för trafikanten och väghållaren

Experiments with some unsalted roads started in 1980 in Sweden and have continued. This report describes the result of studies during the winter 1982/83 regarding road conditions, friction, traffic counts, vehicle stops, resources used by maintenance authorities and intense monitoring of National Road 55. If similar sections with different anti-skid measures (salting and not salting respectively) are compared, the occurrence of icy/snow road conditions is 10-15% greater on the unsalted roads. The experiments also showed that the cost of winter road maintenance may vary greatly between different road sections. The main factors contributing to this difference are: climate, topography, volume and type of traffic, technique and different assessment of the effects of the measures applied. Photography and film evaluation was used in order to monitor stops on hills. Results of snow-clearing, sanding and ice grading are given and it is noted that different types of road pavement can demonstrate large difference in friction under externally similar conditions.
