Do you use salt or grit or both?

Most authorities use pure salt to pre-treat the highway network to mitigate the formation of ice and snow, although traffic is needed to make it effective.In snow

In snow conditions grit is often added to the salt to aid traction. Pure salt is the most effect pre-treatment, grit is often added once snow has started to lay and compact.

The term ‘gritter’ is used generically but most of the time they are spreading salt. In Devon and some other authorities, brine is added to the salt as it leaves the vehicle in what is described as a “pre-wet” operation. This makes the salt quicker acting and it sticks to the road surface.
