Project Details

Project Description: 

The project has three phases: phase I shall consist of identifying appropriate sensing technology, data recording and processing equipment, and making a mockup to verify the measurement system configuration. Phase II will be a followup project to transfer the technology from the laboratory to the field. An appropriate bridge platform shall be identified for this field study in the future by the Federal Highway Administration based on the recommendation from phase I. Phase III will include additional field testing, collection of field data, and modification of sensors and algorithms as needed. In addition, nondestructive evaluation (NDE) techniques suitable for field application will be evaluated.

Goals

The key project objectives are to develop and deploy innovative nondestructive testing (NDT) technologies (Direct Sensing Method) for detecting corrosion damage, and installing corrosion sensing technologies to monitor the internal environment of the main suspension cables (Indirect Sensing Method).
