The rock salt is mined, crushed to appropriate size, and usually applied to roads and highways without further processing. When applied dry, much of the salt can bounce off of the road or be scattered by the wind of passing traffic. If the salt is applied wet, more of it sticks to the road, and the loss of salt is reduced.
