The sand helps melt the ice. I did an experiment. I put three ice cubes in 1 bowl without ice. The other bowl had salt and ice. The one with salt melted the quickest.

Salt water is denser than unsalted (fresh) water.
You can use a magnetic field to move salt water. Magnetohydrodynamics.
Decreases the freezing point of water, so the roads are not as quick accumulate a layer of ice.
salt melts all ice thus clearing the roads for transport
Salt lowers the melting point of ice, so that ice and snow melt and run off the pavement. And if you write in this part, the computer assumes your question has been answered- so when asking a question, please don't do that.
nothing, it's only effective when salt is sprinkled ON the ice.

The salt turns them white.
Rock salt is put on roads to reduce the freezing point of the water thereby reducing icing on roads. This helps to prevent accidents due to skidding and loss of control of the vehicle.
Salt is used to lower the freezing point of water on the roads, preventing ice from forming and helping to melt existing ice and snow. Sand is used to provide traction on icy surfaces, reducing the likelihood of vehicles slipping or skidding. Together, salt and sand help make winter driving safer.
I believe what you are asking is why they salt and/or sand roads. The answer to this, is when it snows, rains, sleets or hails badly, the road becomes slick, so the salt/sand is meant to make it a bit rougher, so the cars don't skid.
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.
Salt is used to melt ice on the roads. Companies like SnowEx make salt spreaders just for this purpose. According to snowexproducts.com, there are a lot of ways to melt the ice on roads. One is salt, others include calcium chloride, Urea, and Magnesium Chloride. In addition to salt, many snow and ice removal companies pre-wet their spreading materials to speed up melting times.
Adding salt(NaCl) to Ice is to take temperature further down.This(Mixture of Common Salt & Ice) is commonly known as 'Freezing Mixture',which may bring down the temperature to as low as (-)20 degree C and very widely used as a Bath for lowering of temp. as well as to keep it cold for longer duration.
