Does salt always melt icy roads?
Salt does not always melt the ice and snow on a road. If real salt (sodium chloride) is being used, the temperature where the salt contacts the ice and snow must be 20 F or higher for it to cause melting. On well traveled roads, the friction from the tires on the road can produce those conditions even if the temperature in general is notably lower, but there will come a temperature, especially in more northern locations, where salt will not work.There are salt substitutes for melting snow and ice, and they work at lower temperatures. Nevertheless, temperatures can drop low enough that even they won't work.That is one reason that highway departments often spread sand before salt or together with salt. The sand helps tires develop friction and hold the road on packed snow, and also absorbs sunlight, increasing the temperatures in the mix on the road.
