Content of Electronic NDT Toolbox
2. Documentation for recommended test procedures, protocols, and available standards and guidelines,
NNDDTTfoforrBBrirdigdegeDeDcekcsk-sS–COSBCectronic NDT Toolbox
1. Summarized information on all recommended methods for bridge deck evaluation, to obtain: a. information about a particular NDT technique, and b. a prioritized list of NDT techniques for different types of deterioration detection.
1. R06B: Evaluating Applications of Field Spectroscopy Devices to Fingerprint Commonly Used Construction Materials
2. R06C: Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurement on New HMA Layers
• Continued support for maintenance and update of the NDToolbox, as the new research, development and technology validation results get available.

Validation Testing
2. Laboratory Component (UTEP) a. 20x8 ft bare deck slab with a series of defects/deteriorations (delamination, vertical cracks, corrosion). b. Section of a real bridge where deterioration and defects determined after testing through autopsies. c. Concentrates on accuracy and repeatability of NDT technologies.
Selection of Deterioration Types
Evaluation of NDT technologies was carried out based on following four deterioration types: • Corrosion • Delamination • Cracking, and • Concrete degradation
