Description:
Deicing agents for regal of ice and snow from highways and streets are considered ssential for wintertime road maintenance in ,most areas of the U.S.A. owever, heavy usage of highway-deicing materials can result in injury and age across a wide environmental. alt-laden runoff from streets, highways, and storage acilities can result in damage to public water supplies, ponds, labs and surface streams; roadside soil, Vegetation and trees; highway structures and pavements; vehicles; and underground utilities. he total annual national cost of salt-related amage is estimated at 5.4 billion dollars. his paper outlines the results of several studies on highway-deicing impacts characterization and control conducted y the U.S. Environmental Protection Agency's (EPA's) research program on urban stormwater and combined sewer overflow pollution control in the 1970's. he idespread environmental impacts from roadway salting are reviewed and recommendations are provided for salt usage, storage, and equipment maintenance. n addition, various methods for anti-icing/deicing are presented. his includes the results of several tudies evaluating and optimizing hydrophobic pavement coating materials. ecommendations for future research to reduce the adverse impact of highway deicing re described.
