ENHANCING ICE-MELTING ACTION OF ROCK SALT BY PREWETTING WITH CALCIUM CHLORIDE

This investigation was prompted by the interest in liquid calcuim chloride (CaCl2) for prewetting rock salt and abrasives used for snow and ice control. The findings demonstrate that prewetting can increase the effectiveness of rock salt and abrasives and thus reduce application rates and costs and may result in decreased damage to nearby salt sensitive vegetation and reduced infiltration into ground water. Both field and laboratory information are included, and both substantiate the increased efficiency of rock salt and abrasives; data indicates that salt use may be reduced by 25-50% and that rock salt may be effectively used at temperatures as low as minus 17.8 deg C (0 deg F). /Authors/
