Synthesis of Service Life Prediction for Bridges in Texas

In procurement requirements for design-build contracts, the Texas Department of Transportation (TxDOT) may implement a 100 year service life requirement for bridge structures. However, there are no indicated measures for how this can be achieved. In addition, for design-bid-build and design-build projects, TxDOT and consultants use TxDOT recommendations for durability to improve service performance. But no quantitative methods or codified guidance is available to demonstrate how the enhanced service life requirements are met. Moreover, because of the large number of existing old bridges, the evaluation of the remaining service life of these bridges is a very important economic problem for TxDOT. As the replacement of all these bridges far exceed the available financial resources, it is important to prioritize the repair works based on the estimated remaining service life. Consequently, this study will conduct a thorough review of the state-of-the-art and state-of practice of bridge service life prediction. The researchers will gather and analyze information related to topic areas including bridge condition inspection, deterioration modeling, and service life prediction. More specifically, they will (1) identify methods to predict service life of bridges over 75 years; (2) identify criteria for evaluating service life of newly constructed design-build and design-bid-build bridges; (3) identify appropriate tests and inspections for determining remaining service life when a bridge is turned back to the owner.
