Project Objectives<br />
1. To identify and characterize rapid NDT technologies for<br />
concrete deck deterioration;<br />
2. To evaluate strengths and limitations of NDT<br />
technologies from perspective of speed, accuracy,<br />
precision, and ease of use;<br />
3. To validate promising technologies;<br />
4. To recommend test procedures and pro<strong>to</strong>cols for most<br />
effective application of NDT methods evaluated<br />
5. To develop an NDT reposi<strong>to</strong>ry for practitioners.

Selection of <strong>Deterioration</strong> Types<br />
Evaluation of NDT technologies was carried out based<br />
on following four deterioration types:<br />
• Corrosion<br />
• Delamination<br />
• Cracking, and<br />
• <strong>Concrete</strong> degradation

Performance measures selected for categorizing and<br />
ranking of technologies:<br />
• Accuracy,<br />
• Repeatability,<br />
• Ease of data collection, analysis and interpretation,<br />
• Speed of data collection and analysis, and<br />
• Cost of data collection and analysis.
