FHWA NDE CENTER RESEARCH & DEVELOPMENT
Nuclear Non-Destructive Testing Laboratory
The Nuclear Non-Destructive Testing Laboratory in the Federal Highway Administration (FHWA) Nondestructive Evaluation (NDE) Center is utilized for inspecting concrete, steel, and asphalt, and the development of new methods. The main instrument of the laboratory is a state-of-the-art X-ray computer tomography BIR-ACTIS system. Other instruments include the chloride detection machine GAMMACHLOR, which was constructed in-house at the FHWA NDE Center.
The following projects are now in progress:
- Determination of crack propagation in concrete using X-ray computed tomography.
- Determination of void percentage and distribution in concrete using X-ray computed tomography.
- Validation of X-ray radiography techniques for inspection of bridge cables.
- Development of codes, standards and specifications for radiography/tomography of concrete.
- Determination of chloride concentration and depth profiles in concrete using Prompt Gamma Neutron Activation Analysis
- Measuring cement hydration using neutron scattering technique.
