Do we still use salt for iced roads?

    Yes.  Salt lowers the freezing point of water.  A solution which is 10% salt and 90% water freezes at 20 degrees Farenheit.  This means if the road is 25 degrees, the salt will lower the freezing point of that water, effecitively causing the ice to revert back into its liquid form.  As such, salt is still the most cost effective method we have of making icy roads safer.  Until a better way is found, I imagine we will continue to rely on salt for icy roads.
