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.

Technologies that define the actual extent of deterioration—beyond what can be seen—for improved repairs and provide real-time solutions.
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.
Using IR scanner for pavement project, Peoria, IL
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.
X-Ray Florescence (XRF)
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.
Ground Penetrating Radar Antenna Array
Information and tools to evaluate pavement smoothness in real-time while the concrete is still wet.
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.
