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.
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.

Guide for Managing Risk on Rapid Renewal Projects, a new SHRP 2 Project Brief
Posted February 18, 2014
Compressing the schedule of transportation design and construction
projects to reduce travel disruption and increase worker safety without
affecting project cost or success can expose a project to risks
different than those that more traditional projects encounter. SHRP 2
Project R09 developed the Guide for Managing Risk on Rapid Renewal Projects
which is accompanied by training materials, forms, and checklists to
assist agencies in implementing the systematic risk management approach
it puts forth. The project brief
describes the Guide and its supplementary materials.

TRB’s SHRP 2 Tuesdays Webinar: Real-Time Smoothness Measurements on Portland Cement Concrete Pavements During Construction (R06E)
March 25, 2014
As part of the SHRP2 Tuesdays Webinar Series, TRB will conduct a webinar on March 25, 2014, from 2:00pm to 3:30pm ET that will summarize the SHRP 2 project Real-Time Smoothness Measurements on Portland Cement Concrete Pavements During Construction
(R06E). 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 SHRP 2 project evaluated the “GOMACO Smoothness Indicator” and the “Ames Engineering Real-Time Profiler” during pavement projects in Georgia, Arkansas, Texas, Michigan, and New York. The project then developed model specifications and construction guidance to expedite the implementation of such technologies.
As part of the SHRP2 Tuesdays Webinar Series, TRB will conduct a webinar on April 22, 2014 from 2:00 pm to 3:30 pm ET that will explore the SHRP 2 project High-Speed Nondestructive Testing Methods for Mapping Voids, Debonding, Delaminations, Moisture, and Other Defects Behind or Within Tunnel Linings
. 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 webinar will summarize SHRP 2 Project R06G
, which identified nondestructive testing (NDT) technologies for evaluating the condition of various types of tunnel linings and tunnel lining finishes. The project then evaluated the applicability, accuracy, precision, repeatability, ease of use, capacity to minimize disruption to vehicular traffic, and implementation and production costs of the identified technologies. The project also advanced hardware and software development for the most promising technologies and proved the validity of the selected technologies to detect flaws within or verify conditions of the targeted tunnel components.

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.
