The Salt transfers heat to the snow and causes the snow to melt and stay at 0C / 32F .
Actually, when you dissolve a salt in water the freezing point of water is lowered (like anti-freeze in your car radiator). So putting salt on snow lowers its freezing point so it melts (unless its new freezing point is higher than the actual temperature, in which case it doesn't).
It's a similar effect to trying to boil water that has a salt dissolved in it. It boils at a higher than normal temperature.

What happens when salt is sprinkled on roads when it snows?
The salt reacts chemically with the water in the snow, lowering its melting point. Depending on outside temp, this may be enough to cause the snow/ice to melt.
