Ohhhhhhhhhhhhh,its snowing!!!!!!

[Dedworth]

I do wish the muppet public when they keep moaning about the councils for not salting the roads would do a bit of research. The salt is to prevent solid ice from forming, if you get a heavy snowfall it will do little until.

The more snow on top, the lower the temperature below, the slower salt works anyway, but unless the frozen water is in direct contact with the salt it will not work, and snow is full of air so little of it touches the salt.

Spot on bit more info here


Why do they use salt to melt ice on the road in the winter?
