DE-ICING CHEMICALS AND ABRASIVES: STATE OF THE ART
THE STATE OF THE ART OF DEICING CHEMICALS AND ABRASIVES FOR WINTER ROAD MAINTENANCE IS SUMMARIZED THROUGH A DISCUSSION OF THE FOLLOWING: PROPERTIES OF DEICING CHEMICALS; ABRASIVES; FACTORS INFLUENCING THE MELTING RATE OF SNOW AND ICE; AND THE RATE OF APPLICATION OF DEICING CHEMICALS. TABLES AND FIGURES ARE PRESENTED WHICH SHOW: (1) THE INCREASE IN THE COEFFICIENT OF SLIDING FRICTION AS ICE IS BEING MELTED BY THE ACTION OF SODIUM CHLORIDE AND CALCIUM CHLORIDE; (2) THE DECREASE IN STOPPING DISTANCE OF AN AUTOMOBILE BY SANDING THE PAVEMENT SURFACE AND BY COMPLETELY MELTING THE ICE OR SNOW (WET SURFACE); AND (3) THE SUITABILITY OF THE VARIOUS TYPES OF CHEMICALS AND ABRASIVES. ESSENTIALLY, THE ABRASIVE WILL PROVIDE IMMEDIATE TRACTION AND INCREASE SKID RESISTANCE, WHEREAS CHEMICALS WILL PRINCIPALLY ACT TO CONTROL SNOW AND ICE CONDITIONS BY (A) PREVENTING THE FORMATION OF ICE FILMS, (B) WEAKENING THE BOND BETWEEN THE SNOW AND THE ROAD SURFACE, (C) MELTING THE FRESH SNOW AS IT FALLS, AND (D) MELTING COMPACTED SNOW THAT REMAINS AFTER PLOWING.
