Renewal
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 Will Launch May 21
Posted May 17, 2013
On Tuesday, May 21, SHRP 2 will launch the NDToolbox—an electronic repository of nondestructive testing (NDT) techniques. Information in the repository 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 in the TRB webinar Nondestructive Testing Technologies for Concrete Bridge Decks (R06A) and by reading Nondestructive Testing to Identify Concrete Bridge Deck Deterioration (SHRP 2 Report S2-R06A-RR-1). On May 21, you can learn how to access the NDToolbox by joining the webinar; a recording will be made available to those who miss the live delivery. A link to the NDToolbox will also be posted to the blurb for the report at a later date.
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.
Preventing Pavement Failure by Identifying Thermal Segregation in Hot-Mix Asphalt
Posted January 25, 2013
Paving contractors have long asked for a tool to keep pavements from failing because of cold spots that form in asphalt mats during the lay-down process. SHRP 2 Project R06C (Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurements on New HMA Layers) demonstrated how infrared and ground-penetrating radar technologies can be used to detect this thermal segregation in hot-mix asphalt and give contractors the chance to correct it during the paving operation. The Texas A&M Transportation Research Institute, which conducted the research, developed an article and a video about their work in this project. Both can be found on the following page.

SHRP 2 Project Brief: Managing Utility Conflicts to Achieve the 3 C’s: Communication, Coordination, and Cooperation
Posted May 6, 2013
When utility relocation is involved, highway construction projects often take longer and cost more. Identifying and resolving potential utility conflicts early in the design process can minimize these delays and costs. Research from SHRP 2’s Renewal focus area (Identification of Utility Conflicts and Solutions Project R15B) developed a comprehensive approach and tools that public agency and utility professionals can use to resolve and manage utility conflicts with new efficiency. This project brief gives an overview of the products.
Technical Summaries Collection for SHRP 2 Renewal Products
Posted November 19, 2012
Our 4-8 page Project Briefs summarize the issues addressed in a research
project, describe the approach to meeting the research objective, and
introduce the resulting products. These technical summaries will be
published for every SHRP 2 project as the final reports are accepted for
publication. The eight existing Project Briefs for SHRP 2 Renewal
research have been collected in the following PDF. Project Briefs are available on the Publications page of the SHRP 2 website.
Older publications are available on the SHRP 2 Publications Page.

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.
