Project C03.2018: Condition Assessment of Corroded Prestressed Concrete Bridge Girders
Condition Assessment of Corroded Prestressed Concrete Bridge Girders
Project C3.2018
Project Summary
The problem we are trying to solve is the condition assessment of corroded prestressed concrete (PC) bridge girders in New England. The problem is important because that PC bridge girders are a critical component of highway bridges. Concrete spalling and prestressing strand corrosion not only cause losses in prestress but also lead to premature failures of PC bridges. We propose to 1) conduct multiphysical field inspection (using 3D photogrammetry, radar, impact-echo, and ultrasound) and to 2) develop an integrated assessment framework for predicting the level of structural damage and prestress losses for PC bridge girders.

Implementation of Research Outcomes:
We have developed a method to control the level of steel rebar corrosion
inside reinforced concrete cylinder specimens in order to subject them to a
pull-out test.
Impacts and Benefits of Implementation:
This project is in its research phase. Impacts and benefits of the research will be reported after the implementation phase.
