The American Association of State Highway and Transportation Officials (AASHTO) Technology Implementation Group (TIG) has been working in partnership with the Federal Highway Administration (FHWA) since 2001 to champion the use and facilitate the implementation of innovative prefabrication in bridges. By moving activities out of the work zone, prefabrication offers a number of advantages to bridge builders, owners, and users, including minimized traffic disruptions, improved safety, minimized environmental intrusion, and improved constructibility. With prefabrication, performance of work in more controlled environments also enhances quality and durability to achieve structures with longer service lives and lower maintenance needs. |
