For conventional post-storm deicing operations, DOWFLAKE™ Xtra Calcium Chloride Flakes may be blended with rock salt to provide faster melting action at lower temperatures than rock salt alone.

Dry calcium chloride/rock salt blends are useful at especially low temperatures and on critical road sections such as bridges, highway ramps, and sharp turns or grades because it can significantly reduce the time required to break the bond between ice and pavement. As the graph shows, this can be an enormous advantage when it is necessary to restore traction in hazardous areas, particularly at temperatures below 15°F.
