Description:
The specific problem to which this report is addressed is the development of a hydrophobic substance to mitigate the adhesion of ice to pavement as an alternative to deicing chemicals. The factors involved in evaluating this concept are the following: Economics; safety; environmental impact; coating effectiveness; potential pavement damage. As a result of this program, two coating formulations (exact formulae are given in Chapter 5 of this report), have been identified as showing considerable promise as semi-permanent, hydrophobic, road coatings with reduced ice adhesion. They are: A modified (no pigment) Federal Specification TT-P-115D traffic paint containing a room-temperature-curing silicone rubber (Dow Corning DC732) as a release agent; and a silicone resin waterproofing compound (Dow Corning DRI-SIL-73) combined with the same silicone rubber as above. One major achievement in this program was the discovery of a method for stabilizing the highly reactive silicone rubber in a fluid solution for spraying.
