Verglimit is a proprietary product that incorporates a special ice-melting chemical (largely calcium chloride) into the asphalt paving mix. The report reviews the performance of an experimental application of a 167-foot test section of Verglimit pavement placed on a city street in Boulder, Colorado in August 1985. The site was evaluated for three years following construction and was photographed with time-lapse cameras for two winters. The subject pavement has proven to be durable but the ice-retardant effects were rarely apparent. This may have been due to periodic sanding and salting of the project location by city maintenance forces. The report recommends the use of Verglimit in high-hazard locations that tend to experience early icing. A previous Colorado test site, which failed due to ravelling, indicates that the material is construction sensitive and care should be taken during its design and placement to achieve proper compaction. Surface slickness during the first few days following construction must also be addressed during construction.
