Deicing operations involve application of chemical freezing-point depressant such as salts to break the bond of already-bonded snow and ice. Different from anti-icing, deicing is a reactive process intended to melt the snow and ice that have accumulated and bonded to the pavement. Deicing is the most widely used strategy in the current practice for snow and ice control at parking lots and sidewalks. The general guidelines for deicing operations as applied to snow and ice control of parking lots and sidewalks are summarized as follows:
Practical lowest effective temperatures of various deicing chemicalsRecommended salt application rates (to be developed)Minimum salt application rates used in highway snow and ice control (from literature) |
