NEW This website was developed to provide highway agencies and bridge preservation practitioners with online resources about bridge preservation, maintenance, and inspection. This online Alkali-Silica Reactivity Reference Center provides users with one-stop access to ASR-related information. The site features an overview of ASR, as well as research reports, specifications, guidance documents, case studies, and links to other useful websites. The FHWA report titled Report on Determining Reactivity of Concrete Aggregate and Selecting Appropriate Measures for Preventing Deleterious Expansion in New Concrete Construction may be accessed and downloaded from this website. Click on Development of ASR Protocols. A new test method, CRD-C 662-09, titled Test Method for Determining the Alkali-Silica Reactivity of Combinations of Cementitious Materials, Lithium Nitrate Admixture and Aggregate (Accelerated Mortar-Bar Method) has been released by the U.S. Army Corps of Engineers and can be accessed at this website. Come join the FHWA's online Information Exchange for Bridges at this website, which offers information on innovative products and processes for bridge construction. The report titled Connection Details for Prefabricated Bridge Elements and Systems is available. Presentations from a monthly seminar series offered online by the Federal Highway Administration National Highway Institute are available to listen to or download from this website.
