Anti-Icing and De-Icing Superhydrophobic Concrete to Improve the Safety on Critical Elements of Roadway Pavements and Bridges

Efficient movement of freight is a vital aspect of America's economy. Weather-related delays to trucking companies cost of 2.2 to 3.5 billion dollars annually. Weather related crashes tend to occur in adverse weather, or on slick roads or pavements. Each year, there are approximately 500 fatalities in the U.S. due to icy road conditions. The worst conditions (black ice) are primarily due to freezing rain and sleet. Existing systems for ice control by heating are relatively expensive and require a power source and the application of de-icing chemicals that lower the freezing point of water require a time lag for deployment. In this proposal, a "smart" Anti-Icing and De-Icing Superhydrophobic Concrete, is proposed to prevent the formation of ice on roadway pavements and bridges. This method involves the engineering of the hierarchical concrete fractured/wearing surface and the application of super-hydrophobic fibers with a siloxane admixture. CFIRE projects 04-09/05-10 provided strong scientific background on a new generation of superhydrophobic fiber-reinforced concrete, with enhanced durability and very large ductility, providing a sustainable material with a service life up to 120 years, which is required for critical parts of concrete infrastructure, especially the components of highway bridges. An experimental program is proposed to develop and establish the feasibility of such a system.
