The research objective of SHRP 2 highway renewal is to achieve renewal that is performed rapidly, causes minimum disruption, and produces long-lived facilities. A related objective is to achieve such renewal not just on isolated, high-profile projects, but consistently throughout the nation’s highway system. Projects that comprise the SHRP 2 Renewal Research Plan are shown in the Projects database, which is organized by project number. Click the project number for a description of the expected project activity.

SHRP 2 NDToolbox Now Available
Posted May 22, 2013
SHRP 2 has launched the NDToolbox—an electronic catalog of nondestructive testing (NDT) techniques. The toolbox includes summaries of NDT technologies; documentation for recommended test procedures, protocols, and available standards and guidelines; samples of data output and guidance on interpreting and presenting results; and equipment features (including cost, availability and specifications). The NDToolbox covers NDT techniques for the following:
• Evaluating concrete bridge decks;
• Using field spectroscopy devices to fingerprint commonly used construction materials;
• Gathering uniformity measurements on new hot-mix asphalt (HMA) layers;
• Identifying delaminations between HMA layers;
• Conducting real-time smoothness measurements on portland cement concrete;
• Continuous deflection pavement measuring; and
• Mapping voids, debonding, delaminations, moisture, and other defects behind or within tunnel linings.
Learn more about the NDToolbox by reading Nondestructive Testing to Identify Concrete Bridge Deck Deterioration (SHRP 2 Report S2-R06A-RR-1).
Utility Conflict Management
Posted January 25, 2013
Achieving the well-known 3Cs (communication, coordination, and cooperation) to reduce time and costs in resolving utility conflicts will be more likely with the new tools and methods developed in SHRP 2 Project R15B (Identification of Utility Conflicts and Solutions). The Texas A&M Transportation Research Institute, which conducted the research, developed an article and two videos about their work in this project. Both can be found on the following page.

As part of the SHRP 2 Tuesdays Webinar Series, TRB will conduct a
webinar on June 3rd, 2014, from 2:00pm to 4:00pm ET that will summarize
SHRP 2 Project R06C:
Technologies to Enhance Quality Control on Asphalt Pavements
; and SHRP 2 Project R06D: Nondestructive (NDT) Testing to Identify Delaminations between HMA Layers
There is no fee to attend this webinar or other webinars in the SHRP 2
Series; however, participants must register in advance. A certificate
for two Professional Development Hours (PDH) will be provided to
attendees who register and attend the webinar as an individual.
reviewed, pilot-tested, and refined two nondestructive
techniques—PAVE-IR and ground-penetrating radar--for detecting defect
areas in asphalt pavements during construction. Recommendations
for equipment and testing protocols were also developed, and a training video
explaining how to use the technologies and interpret the data was produced. Project R06D
reviewed, pilot-tested, and produced guidelines
for using ground-penetrating radar. It also covered impact echo with
seismic analysis of surface waves to detect subsurface delamination in
As part of the SHRP2 Tuesdays Webinar Series, TRB will conduct a webinar on June 10, 2014, from 2:00pm to 3:30pm ET that will summarize SHRP 2 Project R11: SHRP 2 Strategic Approaches at the Corridor and Network Levels to Minimize Disruption from the Renewal Process
. There is no fee to attend this webinar or other webinars in the SHRP 2 Series; however, participants must register in advance. A certificate for 1.5 Professional Development Hours (PDH) will be provided to attendees who register and attend the webinar as an individual. This webinar is pending approval by the American Institute of Certified Planners for 1.5 Certification Maintenance Credits.
produced software to analyze the impacts on road users of multiple, concurrent work zones across a network or complex corridor, and a user’s guide. This tool will help agencies assess the optimal sequencing of renewal projects, and help determine the cost-effectiveness of strategies to minimize, manage, and mitigate road user costs from safety or operational perspectives. The Work zone Impact Strategy Estimator (WISE) software is fully developed and is currently being tested in Iowa and Arizona using historical data to validate its parameters. In addition, pilot tests in New York and Florida will use the software to analyze projects currently in the planning phase.
As part of the SHRP 2 Tuesdays Webinar Series, TRB will conduct a webinar on June 24, 2014, from 2:00pm to 3:30pm ET that will summarize the SHRP 2 project Development of Continuous Deflection Device (R06F)
. There is no fee to attend this webinar or other webinars in the SHRP 2 Series; however, participants must register in advance. A certificate for 1.5 Professional Development Hours (PDH) will be provided to attendees who register and attend the webinar as an individual.
The project produced a report
that catalogues existing continuous deflection measuring technologies and assesses the capabilities of selected devices. It also includes case studies that illustrate the application of the technology for supporting various pavement management decision-making processes and highlight potential future research needs in the area of continuous pavement deflection measuring technologies.

New York Replaces a Bridge in "Two Weekend Nights"
Posted January 30, 2014
A new video highlights the benefits of a SHRP 2 ABC Toolkit for using accelerated bridge construction techniques on standard bridges. Sliding the prefabricated bridge into place over two weekend nights saved millions
of dollars and two years of traffic detours on heavily traveled I-84. Time-lapse photography shows the dramatic results of the project. The SHRP 2 ABC Toolkit and related products are available at http://www.trb.org/Main/Blurbs/168046.aspx.
ENR.com features the ABC Tool Kit in its article, The Top 25 Newsmakers.
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.
Older videos are available on the SHRP 2 in Motion page.
