Over the past ten years, salt consumption for deicing treatment on Swedish roads has been halved from approximately 400 000 tonnes to some 200 000 tonnes per year. This is largely a result of preventive measures with saltsolution, which entails significantly smaller salt doses than in the caseof dry and moistened salt. The purpose of the investigation has been to conduct tests with a salt solution in combination with glucose/fructose in order to determine whether a certain amount of the salt solution can be replaced by a product containing these substances and the kind of technical and environmental effects the mixture would have. The introductory trials,which were performed on an airport landing strip, gave experience of value to the continued testing. They resulted in the surfaces being watered continuously after the solutions had been applied. This led to a leaching ofthe respective solutions with the aim of being able to measure how the friction decreased as the preconditions for the solutions were gradually impaired.
