Bridge Asset Management, based on a degradation model, is a critical tool for entities responsible for the repair and rehabilitation of bridges within their jurisdiction. Bridges commonly show signs of distress due to aging, improper repair, rehabilitation, or lack of proper maintenance. Extending the useful service life of aging bridges is important both to the transportation industry and to governing bodies.
Currently, the greatest problem facing the transportation industry is the degradation of structural components of bridges resulting from both normal deterioration as well as natural disasters. The overuse of bridges beyond their useful service life coupled with improper bridge asset management has exacerbated the situation. This presentation will cover degradation models and demonstrate how the data can be used to develop life cycle models, failures can be directly correlated to changes over time in measurable structural parameters, thus enabling the extrapolation of data to predict when failure is likely to occur.
1. Explain why Bridge Asset Management based on a degradation model is a critical tool for entities responsible for the repair and rehabilitation of bridges within their jurisdiction
2. Identify how to use degradation data to develop life cycle models
3. Discuss bridge inspections
