PERFORMANCE OF TWO ICE-RETARDANT OVERLAYS

The results of tests of an ice-retardant additive blended into plant mixed asphalt concrete are reported. The proprietary product Verglimit, developed in Europe, is designed to prevent formation of ice and to reduce adhesion of snow to the pavement surface during very cold weather. Verglimit is encapsulated in calcium chloride pellets blended into asphalt-cement-concrete top-course material. The test results showed an 86% reduction of ice- and snow-related accidents. The first test site in Albany, showed that the durability of the asphalt overlay containing the additive was equivalent to the normal asphalt overlays. Details of the performance are set forth. The results are also presented of the tests at Binghampton, where more severe tests were initiated. It is noted that ice-retardant overlays perform better in lighter snowfalls than in heavier falls, but always better than conventional mixes. Other conclusions drawn from the studies are also presented.
