Abstract:Verglimit is the name for a multi-component anti-icing flake which is added to an asphalt concrete wearing surface. As tires travel over the road, a chemical is released continuously and retards the formation of ice and snow on the road's surface. Verglimit, which is produced in Germany, has been primarily used in Europe with very favorable reports. It was the subject of an experimental project in Oregon in 1983, with somewhat disappointing results. Oregon chose as test sites two bridges known to have icing problems, the Salmon River Bridge, 12 miles east of Sandy on the Mount Hood Highway, and the Quartz Creek Bridge, 47 miles northwest of Portland on the Sunset Highway. These decks were overlaid with a routine waterproofing membrane and a 1 1/2 inch Verglimit admixture in late September, 1983, with no construction difficulties.
