    • Abstract:
      Life-cycle cost analysis (LCCA) is a necessary component in bridge management systems (BMSs) for

      assessing investment decisions and identifying the most cost-effective improvement alternatives. The

      LCCA helps to identify the lowest cost alternative that accomplishes project objectives by providing

      critical information for the overall decision-making process.

      The main objective of this project is to perform LCCA for different maintenance strategies using the

      developed deterioration models and updated cost data for Nebraska bridges. Deterministic and

      probabilistic LCCA using RealCost software for deck overlay decisions, expansion joint replacement

      decisions, and deck widening versus deck replacement decisions are presented. For deck overlay

      decision, silica fume overlay, epoxy polymer overlay, and polyester overlay are compared against bare

      deck with respect to life cycle cost for variable structural life. In expansion joint replacement decisions,

      two alternatives are compared: relocating abutment expansion joints at the grade beam; and replacing

      abutment expansion joints at the same place. Deck widening is compared with deck replacement in five

      different bridges.
