Winter service evolves over the years with ongoing development and research. This topic covers all subjects concerning innovation in techniques and technologies in winter service. New techniques such as application of de-icers and anti-icers, improvement in the use of abrasives, snow and ice clearance procedures and methodologies and sustainable and adaptive maintenance procedures are one part. Also new technologies like new snow and ice clearing equipment, automation of snow and ice control, new or alternative chemicals or materials and sustainable products or equipment are developed. De-icing chemicals play a major role in winter service and help provide traffic safety. Sodium chloride is the major de-icer used against snowy or icy roads with very good results. As it is not free of side effects alternatives are tested and analysed. This session provides an overview of de-icers.
