SHRP 2 in Motion
When SHRP 2 research can be captured in a way that is visually interesting, we’ll post it here. Please send your comments to pzelinski@nas.edu. A Flash player is necessary to view the videos. You can download a Flash player for free at http://get.adobe.com/flashplayer/.
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.
Video Demonstrations of Three SHRP 2 Products Now Available
Posted February 3, 2012
Step-by-step demonstrations narrated by the principal investigators of three SHRP 2 products that were featured in the SHRP 2 booth at the 91st TRB Annual Meeting are now available on the SHRP 2 website:
• Geotechnical Solutions for Transportation Infrastructure: a web tool that provides guidance for soil improvement, rapid embankment construction, and stabilization of the pavement working platform
• Transportation Project Impact Case Studies (T-PICS): a national database of case studies that can be used to assess the pre- and post-construction economic development and related effects of various kinds of transportation projects
• My Road Trip Advisor: a tool that predicts arrival times for travelers based on travel time reliability information
The videos are 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.
Video: Michigan DOT Director Kirk Steudle Explains SHRP 2
Posted October 6, 2010
A video is available from the Institute of Transportation Engineers of an interview with Kirk Steudle, chair of the SHRP 2 Oversight Committee and director of the Michigan Department of Transportation. In the video, Steudle explains how SHRP 2 is a reaction to the state of practice of transportation in the U.S. today. Steudle also discusses what the expected outcomes of SHRP 2 research are, how these outcomes are emerging from thought into reality, and what these developments may mean for transportation engineers.

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.

Demonstration: Infrared Bar for QC/QA, conducted as part of Renewal research project R06C: Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurement on New Hot Mix Asphalt Layers
Posted November 19, 2009
This video shows a demonstration of an infrared bar being used for quality control and measurement of new hot mix asphalt layers during paving operations. This demonstration was part of Renewal Project R06C: Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurement on New Hot Mix Asphalt Layers. This project is demonstrating these technologies to assess hot mix asphalt density and segregation in the four AASHTO regions, and will recommend how these technologies can be incorporated into existing department of transportation specifications for construction quality assurance.
