Abstract

It has been the practice of highway maintenance engineers among certain northern states to use calcium or sodium chloride for treatment of icy pavements during the winter months. These materials are usually added to sand or cinders and the mixture spread upon the travelled surface. They serve to lower the freezing point and embed the abrasive particles in the ice, thus rendering the surface non-skid. considerable diversity of opinion, however, has existed concerning the most effective manner in which these salts should be used, whether they damage the surface of concrete pavements, and their relative ability to melt ice.
