Here they're using some sort of brine or something on the highways - does a better job melting I guess, but more importantly, if cars drive over it, it doesn't get thrown off the road surface the way salt does before it starts integrating. Seems like the road are a lot less dusty at the end of the season. In town they still use the rock salt type stuff, though, although in my town it's the green stuff in a lot of areas.
