Pre-wet cuts out the Highland fling

This article looks at the winter road maintenance services provided by the new operator in the north-west Highlands of Scotland. Staff operate from thirteen depots, with overnight patrols, and a 24-hour control room run from one of six depots on a rota. Up-to-date forecasting of weather is essential, and road-based sensors, weather detectors and infra-red webcams provide additional timely information. The policy is to start treating routes three hours before the forecast time of the onset of bad weather. Pre-wetted salt was chosen as the road treatment option to reduce wastage and improve control of spread rate. Ten salt saturators were installed, using high purity salt to produce brine. New de-icing spreader vehicles were bought, featuring global positioning system technology to monitor and control spread rate, and track vehicle movements.
