CHEMICAL MELTING OF ICE AND SNOW ON PAVED SURFACES

WHEN IT IS IMPOSSIBLE TO REMOVE ICE FROM PAVED SURFACES BY MECHANICAL MEANS, CHEMICAL AGENTS ARE EMPLOYED EITHER TO COMPLETELY MELT THE ICE OR TO PARTIALLY MELT IT SO THAT IT CAN BE BROKEN UP AND REMOVED BY BROOMING OR SCRAPING. CHLORIDES, WHICH HAVE LONG BEEN USED FOR THIS PURPOSE, ARE OBJECTIONABLY CORROSIVE. UREA, WHICH IS ALSO WIDELY USED, IS INEFFECTIVE BELOW THE EUTECTIC TEMPERATURE OF 11 F AND IS MARGINALLY EFFECTIVE BELOW 15F. A NONCORROSIVE LIQUID AGENT HAS BEEN FORMULATED FOR USE AT TEMPERATURES DOWN TO 0 F. DURING THE WINTER OF 1969 AND 1970 THE AGENT WAS TESTED AT LAGUARDIA AIRPORT IN NEW YORK AND AT UNION CARBIDE LABORATORIES. RESULTS OF THESE TESTS ARE REPORTED. /AUTHOR/
