Innovative Bridge Designs for Rapid Renewal (SHRP 2 Prepublication Report*)
|
|
Greetings!
Accelerated bridge construction (ABC) techniques have the potential to minimize traffic disruptions during bridge renewals, promote traffic and worker safety, and also improve the overall quality and durability of bridges. To make ABC techniques more applicable to typical bridges, SHRP 2 Project R04 (Innovative Bridge Designs for Rapid Renewal) developed standardized and scalable approaches to designing and constructing complete bridge systems for rapid renewals. The final report documents the development of those approaches, describes a demonstration project that was completed in 2011 using the ABC standards developed in this project, and introduces the Innovative Designs for Rapid Renewal Toolkit, which is available as a separate document. The Toolkit includes design standards and design examples for complete prefabricated bridge systems, and it proposes specification language for accelerated bridge construction systems suitable for future inclusion in the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design and Construction Specifications.
* To make research available as early as possible, SHRP 2 is temporarily posting final reports that have been submitted by the research team, reviewed according to the relevant National Academy of Sciences procedures, and accepted for publication. These prepublication drafts, which have not been edited or formatted for publication, will be replaced by the final versions as they complete the editorial process.
