Preventing and mitigating alkali-silica reactivity (ASR) in portland cement concrete pavements and structures is the focus of a new $10 million Federal Highway Administration (FHWA) initiative. The 4-year ASR program was established and funded by the 2005 Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). "This new highway concrete technology program is designed to increase concrete pavement and structure durability and performance and to reduce life cycle costs through the prevention and mitigation of ASR," says Gina Ahlstrom of FHWA's Office of Pavement Technology.
