For today's road authorities it is very important to keep track of the quantity of chemicals used in winter road maintenance. Variations in snow and ice conditions from year to year make it difficult to compare figures. In order to tackle this problem, the Swedish Road Administration (SRA) has developed a new Salt Index. This provides a good basis for comparing salt consumption from year to year and a possibility to identify areas where too much salt is used for the prevailing weather conditions. An analysis of maintenance costs and benefits in total in 2004 showed some interesting results concerning winter maintenance in general and salt consumption in particular.
