Putting winter to the test

摘要

The NWSRG is on a mission to expand its influence across the sector. Its research could have an international impact and some of its most interesting work is happening in Scotland, most notably the well-publicised brine versus pre-wetted salt trials, which are due to start again this winter. Mr Thomson gives Highways an update: Phase 4 trials are due across 2017/18 winter. The criteria for the Phase 2 and 3 trials was to use brine for precautionary treatments on damp or wet roads to -5℃. The results of these two phases demonstrated that brine provided an effective service in these conditions and brine spreading was a suitable treatment on the majority of days when spreading occurred on the trial sites.
