SHRP2 Nondestructive Testing Solutions NDE Web Manual

 

FHWA’s Nondestructive Evaluation (NDE) Web Manual allows users to search for technologies relevant to specific materials, types of deterioration, and/or infrastructure elements. It includes also best practices, sample applications, and performance attributes of various technologies.

  
New nondestructive testing (NDT) solutions to better construct and maintain America’s roads, bridges, and tunnels.
  • Geophysical, mobile-scanning, and hand-held technologies to help inspect concrete bridge decks or tunnel linings more quickly and comprehensively.
  • Tools to detect project-level pavement delamination and debonding early on in a project.
  • Infrared and radar technologies that provide real-time testing of nearly 100 percent of the pavement area during construction.
  • Market-ready technologies that provide real-time verification to ensure construction materials meet specifications.
  • Proven technologies to help improve concrete pavement smoothness during construction.
  • Advanced utility identification technologies to detect, locate, and characterize subsurface utilities.

To learn more about the NDT solutions offered through the SHRP2 program, read our Nondestructive Testing Solutions brochure.

 
Nondestructive Testing for Concrete Bridge Decks and Tunnel Linings (R06 A/G)

Technologies that define the actual extent of deterioration—beyond what can be seen—for improved repairs and provide real-time solutions.

  • Geophysical technologies for evaluating and inspecting concrete bridge decks; mobile-scanning and hand-held technologies for mapping voids, debonding, delaminations, moisture, and other defects behind or within tunnel linings.
  • For more information, visit the R06 A/G product page.
  • Current states using R06A: Alabama, Arkansas, California, Delaware, Florida, Georgia, Hawaii, Indiana, Iowa, Kentucky, Louisiana, Missouri, Nebraska, New Mexico, New York, North Carolina, North Dakota, Oregon, Pennsylvania, and Virginia; current states using R06G: California, Colorado, Oregon, Pennsylvania, and Virginia.

Rapid Technologies to Enhance Quality Control on Asphalt Pavements (R06C)

Two products aimed at providing real-time testing of potentially 100 percent of the pavement area, providing much more inspection coverage than existing methods for Asphalt Pavement construction.

  • Through an equipment purchase and demonstration program, showcase, and targeted workshops, states participating in the Implementation Assistance Program (IAP) are receiving hands-on experience using these technologies under varying conditions.
  • For more information, visit the R06C product page.
  • Current states using R06C (IR): Alabama, Alaska, Illinois, Maine, Missouri, New Jersey, North Carolina, Virginia, and West Virginia; R06C (GPR):   Nebraska, Maine.

Techniques to Fingerprint Construction Materials (R06B)

Two market-ready technologies—X-ray Fluorescent Spectroscopy (XRF) and Fourier-Transform Infrared Spectroscopy (FTIR)— that can be used during construction to verify the chemical compounds or presence of certain additives or contaminants in some commonly used construction materials.

  • Through Round 7 of the IAP, selected transportation agencies will have the opportunity to assess these technologies using different methodologies on different materials under varying field experiences.
  • For more information, view the R06B fact sheet
  • Current states using R06B are Alabama, Maine, and Tennessee.

X-Ray Florescence (XRF)

 
Advanced Methods to Identify Pavement Delamination (R06D)

Three technologies – GPR and IE technology, combined with the Seismic Analysis of Surface Waves (SASW) system – to detect project-level pavement delamination and debonding before the deficiencies cause visual pavement distress.

  • Through Round 7 of the IAP, selected transportation agencies will have the opportunity to use these technologies on their projects.
  • For more information, view the R06D fact sheet.
  • Current states using R06D are California, Florida, Minnesota, New Mexico, and Texas.

Ground Penetrating Radar Antenna Array

 
Tools to Improve PCC Pavement Smoothness During Construction (R06E)

Information and tools to evaluate pavement smoothness in real-time while the concrete is still wet.

  • Through equipment loans and demonstrations, states participating in the Implementation Assistance Program (IAP), along with a number of non-IAP participating states, are receiving hands-on experience using these tools, along with training.
  • For more information, view the R06E fact sheet.
  • Current states using R06E: Alabama, Idaho, Indiana, Ohio, and Pennsylvania. Technical assistance is available to support additional agencies if requested.

Utility Locating Technologies (R01B)

Two advanced utility identification technologies that may help transportation agencies looking for more detailed information than previously known about their subsurface utilities. The first is Multi-Channel Ground Penetrating Radar (MCGPR). Since this technology does not work well in clay soils, a second technology was identified in the research. Time Domain Electromagnetic Induction (TDEMI) can work in highly conductive soils; however, it cannot detect non-metallic utilities without a tracer wire. Soil type, terrain, and other geophysical attributes will help determine which technologies are appropriate for a given location.

  • Through an equipment purchase and demonstration program, and technical assistance, states participating in the Implementation Assistance Program (IAP) are piloting these advanced utility investigation technologies.
  • For more information, visit the R01A/R01B/R15B product page.
  • Current states using R01B:  Arkansas, California, Indiana, Montana, Ohio, Oregon, and Virginia.
