Abstract

Calcium or sodium chloride has been used for treatment of icy pavements. 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 chlorides should be used, whether or not they damage the surface of concrete pavements, and their relative ability to melt ice. Progress reports of methods in practice for treatment of icy pavements and investigations using concrete specimens of 28 days and six months of age have been presented in the tenth, eleventh and twelfth annual proceedings of the Highway Research Board. This report reviews the previous reports and presents the results of tests on concrete specimens one year of age, together with the recommendations of the committee.
