Non-Destructive Evaluation (NDE) Scanning and Photogrammetric Data Fusion for Concrete Bridge Assessment and Quality Assurance (QA) of Repairs

Program Description

Concrete repair projects increasingly benefit from the use of nondestructive evaluation (NDE) methods to diagnose and identify where internal concrete conditions need repair. By overlaying the results from multiple NDE methods, a data fusion approach provides a more accurate surface and full-depth image of concrete bridge conditions for repair designs. NDE is also increasingly being used for QA of repairs.

Learning Objectives

Through participating in this program, attendees will understand...

1. Nondestructive test (NDT) methods for concrete evaluation, including ground penetrating radar, impact echo, spectral analysis of surface waves, and photogrammetry.
2. Industry guidelines regarding NDT.
3. The significance of using a data fusion approach for evaluation of concrete bridge girders and decks.
4. Case studies of the approach on a post-tensioned concrete bridge in a marine environment and bridge deck scanning for corrosion delamination mapping for repairs
5. NDE for QA of epoxy injection repairs to pre-stressed bridge girder
