Global Positioning System–Controlled Salt Spreading: From Idea to Implementation

Salt spreading controlled by Global Positioning System allows salt distribution on the whole road surface with automatic adjustment of spreading dosage, width, and symmetry while the driver concentrates on following the route. This technology is developed because automatic data collection from salt spreaders has shown that even skilled drivers can’t adjust spreading width and symmetry in a proper way and drive the truck at the same time. In the long term the technology is essential to implement salting with different dosages based on prognoses for the salt needed along a route. Today the same dosage is used on the entire route even though we know that the salt needed won’t be the same.
