High‐Performance Concrete: Applying Life‐Cycle Cost Analysis and Developing Specifications

Numerous studies and transportation agency experience across the nation have established that high‐performance concrete (HPC) technology improves concrete quality and extends the service life of concrete structures at risk of chloride‐induced corrosion. The feasibility and benefits of using HPC in Arizona bridges were demonstrated in Arizona Department of Transportation's (ADOT’s) Sunshine Bridge project, after which ADOT wanted tools for determining when and how to use HPC in other bridge projects. One such tool would be life‐cycle cost analysis (LCCA) software to help in selecting the optimum HPC solution. Another tool would be a set of draft HPC prescriptive specifications –for full deck replacement and for overlay repair – that contractors could use to incorporate HPC solutions in building and repairing ADOT bridges. This project determined that, as LCCA software, the Life‐365 Service Life Prediction Model™ was a viable option for estimating life‐cycle costs of bridge decks where salt (chloride) is applied to control the accumulation of ice. Also developed for ADOT’s use were draft specifications for using HPC on full bridge deck replacement and on overlay repair.
