No one really invented it. For many years, salt has been known to lower the freezing point of water. This happens when the salt's ions dissociate in water. The act of lowering a freezing point (or raising a boiling point) is called water's colligative property. Generally speaking, the more ions in solution, the lower temperature at which water will freeze. The salt used on roads is usually calcium chloride (CaCl2).

Why does salt sprinkle on ice roads cause ice to melt?

Sprinkling salt on icy roads doesn't warm up the ice. What it does is depress the freezing point of water to the point where the ice is too warm to be solid, even though it is just as cold as before.
