An Evaluation of the Use of Liquid Calcium Chloride to Improve Deicing and Snow Removal

Report No: 78-R48

Published in 1978

About the report:

The Iowa method of spraying liquid calcium chloride onto sodium chloride applied in snow and ice removal operations was evaluated on four sections of highway in the Staunton District. From the relatively sparse data accumulated over three winters, it was concluded that the slight advantage gained through use of the method was offset by the additional cost and trouble entailed. However, it was noted that the prewetted salt adhered to glare ice better than did the unwetted salt, and it is recommended that the mixing tanks used in the evaluation be left in place to supply liquid calcium chloride for use on salts applied to glare ice.
