Wonder how it would work on roads. Something has to be better than the stuff they use now. In Wisconsin the roads are often a mess from buckling during weather changes and lots of pot holes that they are always having to fill in. Much of the time a road will go for years before it is repaired when it needs it. I think it might be a rip off scheme from the construction companies to keep them in constant work while they suck up our tax dollars. Sometimes the lowest bid is not the best idea if it means inferior product is used.
You put salt on the roads there don't you? I would suspect it's the salt.
