About the research

Research objective: This work will develop design recommendations to minimize differential deck panel deflection, which has been shown to be one source of deterioration of asphalt wearing surfaces on these panels. In addition, this research will seek out a bridge owner with a bridge with a history of differential panel deflection induced deterioration. The research team will work with the bridge owner to implement a repair/rehabilitation scheme.
