SPR-5130: Computational Tool for Estimating the Service-Life of Concrete Decks and Slabs

The objective of this implementation project is to deliver a calibrated and accessible computational tool that the Indiana Department of Transportation (INDOT) can use to estimate the service life of concrete bridge decks, one-way continuous solid slabs, and T-beam bridges, and to evaluate maintenance and rehabilitation scenarios. The model methodology, developed under Joint Transportation Research Program (JTRP) projects 4840 and 4526, captures the long-term effects of construction defects, environmental exposure, and common maintenance actions on deck performance, enabling prediction of the evolution of deck condition ratings under different deterioration and intervention scenarios. A user manual and user interface will be developed, and several illustrative case studies will be prepared.
