Decreasing/Lowering of freezing point is the phenomenon.
When impurities or external substances are mixed in a liquid, its freezing point decreases. and the Boiling point increases. This is related to concentration of the solute.
Thus salt mixes with ice or snow. As the melting point is lowered the snow melts even at temperatures less than 0 ° C.
That helps towing away of snow from roads and pedestrian paths. Snow doesn't allow cars to go fast as there is no friction. So cars skid. So snow must be removed. But snow is heavy and is difficult to push.
