The Long-Term Bridge Performance (LTBP) programme will involve the collection and analysis of performance data on selected US bridges to understand how they react under given conditions. The data will be used for a variety of purposes, including the study of deterioration and durability and the impacts of maintenance and repair. Researchers expect the programme to provide a better understanding of deterioration, including the effects of corrosion, fatigue, environmental conditions and loadings.

The work will be carried out by a broad-based team assembled by CAIT representing state, local, and federal agencies, industry and academia.
