TRB’s second Strategic Highway Research Program (SHRP 2) SHRP 2 Report S2-R04-RR-2: Innovative Bridge Designs for Rapid Renewal: ABC Toolkit describes standardized approaches to designing and constructing complete bridge systems for rapid renewals.
The report includes design standards and design examples for complete prefabricated bridge systems, and proposes specification language for accelerated bridge construction systems, which adheres to the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design and Construction Specifications.
The R04 MathCAD files
for the SHRP 2 Report S2-R04-RR-2 are available to help illustrate the sample accelerated bridge construction (ABC) design calculations. The sample design calculations serve as training tools for engineers to increase familiarity with ABC design issues and criteria.
A demonstration project on US 6 over the Keg Creek near Council Bluffs, Iowa used the accelerated bridge construction standards developed as part of Renewal Project R04.
The following three videos were produced related to the Keg Creek project:
• ABC for Everyday Bridges
(18:39) highlights the specific techniques used to deliver a new bridge with only a 10-day closure.
• One Design—10,000 Bridges
(9:46) describes a tool kit for designing and constructing bridges that brings home the benefits of accelerated bridge construction techniques so local contractors can use typical equipment to build bridges quickly and efficiently.
• Time-Lapse Video
(1:30) shows ABC techniques being used by a local contractor with standard equipment to replace the Keg Creek three-span bridge.
A second demonstration project on I-84 in New York also used the ABC Toolkit in applying bridge slide technologies, which were used over two weekend nights to save millions of dollars and two years of traffic detours. The "Two Weekend Nights" video
documents the successful use of the technology.
SHRP 2 Renewal Project R04 also produced the Innovative Bridge Designs for Rapid Renewal
report that documents the development of standardized approaches to designing and constructing complete bridge systems for rapid renewals.
In June 2013, SHRP 2 produced a Project Brief
on the project that developed the ABC Toolkit.
