Abstract Full-depth precast concrete (FDPC) deck panels are becoming more popular recently as they can accelerate construction. However, there are still concerns about durability, proper connections, and long-term performance that have limited their widespread use in the U.S. Most studies on FDPC deck panels have been on their short-term structural performance and joint behavior; there is minimal published work addressing the long-term performance of these structures. A survey was developed and sent out to all state departments of transportation (DOTs) for the work described in this paper. The information gathered from this survey included: a list of bridges using FDPC deck panels (with details about projects), cost, observed performance, experience with panels, and types of joints used. The FDPC Deck Panel Database was developed based on the collected information from this survey and combined with information from the National Bridge Inventory (NBI) database. The performance of bridges in the database was evaluated based on the deck deterioration rate and estimated service life according to simple linear regression and a deep learning models provided by Long-Term Bridge Performance (LTBP) InfoBridge. The result of this effort was identification of the performance of bridges with FDPC deck panels under different conditions. Joint type, traffic impact category (i.e., time construction impacts traffic), climate zone, wearing surface type, and traffic were found to impact the behavior of bridges with FDPC deck panels. Construction type (new construction versus rehabilitation) did not influence the behavior of these bridges.
