Placement of an Experimental Bituminous Concrete Mixture Utilizing an Asphalt Additive - Verglimit

摘要

The pavement overlay incorporated the additive 'Verglimit.' Composed of Calcium Chloride and Sodium Hydroxide encased in linseed oil, this capsule-like material is added to the bituminous mix during production. Once in place as pavement, the Verglimit is designed to retard the formation of ice on the friction surface, particularly on bridge decks. ConnDOT has placed approximately 85 tons of Verglimit mix on one side of a newly constructed bridge, using the other as a control. Construction difficulties and material costs are addressed in the report. The pavement durability and ice-retardant capabilities of the Verglimit mix will be evaluated for a period of five years.
