TRUE GRIT IN GRAMPIAN

This article discusses several possibilities for more cost-effective use of salt to keep roads open during winter weather, and reports the results of some relevant research undertaken by the Grampian Region of Scotland, in collaboration with Aberdeen University. The author estimates that on average over 2 million, of the 25 million spent annually on road salting in the UK, is wasted. Correct calibration of the width of gritting and the amount of salt spread per square metre considerably increases the length of road that is protected from icing and substantially reduces the cost of protection per mile; the use of calibration can reduce the amount of salt required by as much as 50%. Large gritting machines are not always the most efficient, and it is best for a local authority to use a fleet of vehicles of mixed sizes, whose use would be matched to requirement to provide a safe service to the community. The use of well-graded grains of salt provides further savings, as better results are obtained by using a consistent quality and particle size of salt in the gritter. Demountable machines with a quick change body system are the most effective specialist highway maintenance equipment for use at all times of the year.
