Mechanical Integrity and Sustainability of Pre-stressed Concrete Bridge Girders Repaired by Epoxy Injection - Phase I

In view of the research needs stated above, the project objectives are to: (1) Explain in which conditions the strength of cracked concrete can be recovered by epoxy injection; (2) Design the injection method for optimal mechanical performance; (3) Interpret mechanical tests performed on cracked and repaired pre-stressed concrete beams; (4) Assess the mechanical integrity of pre-stressed bridge girders for a variety of crack and injection patterns; (5) Predict the mechanical behavior of repaired concrete in the long-term, under typical loading and weathering conditions; (6) Simulate the life cycle of a typical pre-stressed girder; (7) Assess the sustainability of pre-stressed concrete bridge girders repaired by epoxy injection.
