Salt is the most widely used de-icing agent for road maintenance in Europe and is used for:
Anti-icing: This refers to the application of pre-wetted salt or brine to enhance the grip between tyres and the road surface.
De-icing: This applies to the application of dry salt or pre-wetted salt. Depending on the sort of salt used, it is usually heated or diluted. In melting snow, de-icing salt is the most efficient agent as long as the pavement temperature isn’t below -18°C.
Salt is considered the best de-icer due to its properties. It has the power to lower the freezing point of water and therefore prevents a bond between ice and road surfaces.
