WeatherWhys for January 17,2014 from accuweather.com
Road salt effectively removes ice and snow from highways and sidewalks.
When applied, the chemical properties of salt lower the freezing point
of water. In turn, the ice and snow become liquid water even though the
air temperature may be well below freezing. However, salt loses its
melting power in extremely cold conditions.
