Back down to earth a new road salt has been created to work in temperatures as low as -20 degrees Celsius and has received the thumbs up for use on Scottish roads. The road salt comes in liquid form like a de-icer, a mix of salt and magnesium chloride. It has proven effective at melting hard packed snow and ice in extreme cold. Regular salt only works down to -8 deg C. They are building up reserves at key motorway sites but there is a bit of a downside. The so-called Supersalt costs 12 times as much as the conventional salt. In December much of Scotland ground to a standstill when temperatures dropped to -25 deg C. Can’t see many English authorities being willing to stump up the sort of money that it would cost to replace the traditional road salt. What do you think? Should the authorities be willing to spend the extra? By Graham Hill
