The primary objective of this research was to evaluate the product performance, safety, and maintenance benefits associated with the Cargill SafeLane anti-icing pavement overlay system through field tests and evaluation of crash reduction statistics.
The winter performance of the SafeLane commercial overlay system was evaluated at four installations on bridge decks in the state of Minnesota. The study was conducted over a period of three years. Analyses included mechanical and chemical testing of the components, chloride analysis as a function of depth, friction by skid test and visual inspection. At one site, plow operator comments were gathered to access retention of de-icing chemicals from event to event. All sites were included in a comparison of accident frequency before and after overlay installation.
