While most local roads are maintained by Aberdeenshire Council, BEAR Scotland looks after and salts the trunks roads.
The winter service runs from October 1 until May 15, but can be extended beyond these dates. The focus is to carry out precautionary treatment to prevent ice forming.
Current road surface temperatures and road conditions are monitored through the Vaisala Road Weather Information System using 31 roadside weather stations throughout the North-east trunk road network.
Between November 1 and March 31, conditions are monitored from the winter control room on a 24/7 basis. The dedicated spreaders used for precautionary treatments and patrols are equipped for pre-wetted salting. Brine is mixed with the dry salt immediately prior to spreading to help it stick to the road surface and start the melting process.
BEAR Scotland has four snow blowers in the North -east. These all-wheel drive vehicles are capable of moving up to 600 tonnes of snow per hour. There are 25,000 tonnes of salt in the North East Unit ready for the start of the winter service period.
