From page 13...
... Pavement surface temperature has a major effect on how ice control chemicals perform and ultimately, on the treatment decision itself. As pavement temperatures decline below about 12°F, most ice control chemicals become very inefficient because of the slow melting rate and the amount of ice melted per unit of chemical applied.

From page 14...
... Fine graded salt applications are not well suited for deicing operations because of the high dilution potential. 14 Solid ice control chemicals are often mixed in small quantity (less than 10 percent)
