SHRP 2 Project Brief: A Toolkit for Accelerated Bridge Construction
|
|
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. This project brief gives an overview of SHRP 2 Project R04: Innovative Bridge Designs for Rapid Renewal, which developed standardized approaches to designing and constructing complete bridge systems. This project created the SHRP 2 ABC Toolkit, which includes recommended design standards and design examples for complete prefabricated bridge systems for routine bridges with span lengths from 40 ft to 130 ft. The Toolkit also includes recommended specification language for ABC systems 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. The ABC design standards developed in this project were used in pilot projects in Iowa, New York, and Vermont.
