Two weeks? That really is accelerated bridge construction
Posted October 26, 2011
Bridge designs developed in a SHRP 2 Renewal project are taking shape over the Keg Creek in Iowa this week and next. The designs combine several innovations into standardized approaches that can be easily adjusted to meet the requirements for nearly any bridge project, making the benefits of rapid renewal, economies of scale in manufacturing and construction, reduced traffic disruption, and increased safety widely available.
To demonstrate the design using accelerated bridge construction (ABC) techniques, SHRP 2 is working with Iowa DOT to replace a three-span 210 ft x 47 ft bridge steel/precast modular structure with precast bridge approaches on US 6. Using traditional construction methods would require road closures for several months, but using the SHRP 2 design with ABC techniques will limit the road closure to only two weeks. The Iowa DOT is hosting a project website that provides more information, including a live web camera of the construction, photos, videos, plan drawings, and technical information. SHRP 2 is also producing a documentary video to promote the innovations being demonstrated on this project.

Tomorrow’s Bridges: A Renewal Project Brief Summarizing Bridge Research in SHRP 2
Posted April 26, 2011
A new project brief, Tomorrow’s Bridges,
describes how SHRP 2 is working to turn today’s innovative bridge
technologies into tomorrow’s bridge standards. The brief summarizes
expected products from SHRP 2 to improve bridge foundations, bridge
design and components, bridge construction, bridge design codes, and
bridge deck evaluation.

Presentations from the First International Symposium on Long-Lived Bridges
Posted June 30, 2010
The first International Symposium on
Long-lived Bridges was held on June 8 and 10 in Brussels, Belgium,
during TRA 2010. This was the third symposium organized in
collaboration with the Forum of European National Highway Research
Laboratories (FEHRL).
A summary of the symposium and the presentations are now available.

Renewal and Implementation Activities of SHRP 2
Neil Hawks
|
In August SHRP 2 Director Neil Hawks attended the final conference
on the Assessment and Rehabilitation of Central European Highway
Structures (ARCHES) and Sustainable Pavements for European New Member
States (SPENS) research projects on bridge and pavement research in
Ljubljana, Slovenia. These Renewal-related research programs were
sponsored by the European Union and managed by the Forum of European
Highway Research Laboratories (FEHRL). Neil Hawks’ presentation included
information about SHRP 2 projects—on modular pavement technology,
railroad/DOT coordination, and bridges designed for 100+ years of
service life—and plans for implementation. A video of the lecture is available.

ABC for Everyday Bridges
Posted March 1, 2012
This video
shows how typical bridges can be replaced quickly and cost-effectively
with accelerated techniques that do not require special equipment. More
than the overview of the Keg Creek bridge replacement project shown in
the companion video One Design--10,000 Bridges, ABC for Everyday Bridges
highlights the specific techniques used to deliver a new bridge with
only a 10-day closure. The design tool kit used in the project was
developed through the second Strategic Highway Research Program, a
division of the Transportation Research Board.
Video: One Design—10,000 Bridges
Posted February 16, 2012
Thousands of bridges across America must be replaced. A new tool kit for
designing and constructing bridges brings home the benefits of
accelerated bridge construction techniques so local contractors can use
typical equipment to build bridges quickly and efficiently. Developed
through the second Strategic Highway Research Program, a division of the
Transportation Research Board, the tool kit was demonstrated in
construction of a bridge over the Keg Creek near Council Bluffs, Iowa.
The design reduced the road closure to only two weeks from a more
typical 6 months. Time lapse photos at the end of the video show the
construction. The video is available on the following page.
Time-Lapse Video of Keg Creek Bridge Replacement
Posted December 8, 2011
This time-lapse video shows accelerated bridge construction (ABC)
techniques being used by a local contractor with standard equipment to
replace a three-span bridge on U.S. 6 over the Keg Creek in
Pottawattamie County, Iowa. This demonstration was part of a SHRP 2
Renewal research project which created standard bridge designs that can
be adapted to a large number of bridge projects. The design scales ABC
methods to typical projects so that the benefits of faster construction
and advanced materials can be replicated wherever possible. The goal is
to make ABC techniques a standard part of bridge construction. The video
is available on the following page.
Video: Field Validation Tests of Nondestructive Testing Technologies on a Concrete Bridge Deck
Posted July 12, 2011
In October and November of 2010, 20 nondestructive testing (NDT)
technologies were evaluated during tests on a concrete bridge deck in
Haymarket, Virginia, as part of a SHRP 2 research project. This research
project is being conducted by Rutgers University with the University of
Texas at El Paso and the German Federal Institute for Materials
Research and Testing. Teams from industry and academia demonstrated how
their NDT technologies —such as ground-penetrating radar, impact echo,
and infrared thermography—can be used to detect deterioration in
concrete bridge decks. Video segments of the tests are included on the
following page.
