22-01 — Recent Leading Innovations in the Design, Construction and Materials Used for Concrete Bridge Decks

Original Scope: Deterioration of concrete bridge decks due to corrosion of steel reinforcement is a long-known cause of limited-service life and increased maintenance costs of bridge structures. To address these issues bridge owners have implemented a variety of strategies such as the use of fiber-reinforced concrete, performance-based concrete mixes, FRP composite reinforcement, modified curing regiments, deck sealers, shrinkage reduce admixtures, partial or full precast decks, and prestressed concrete. Agencies are anxious to identify appropriate strategies based on environmental variables and service demands that will extend the service life and save significant costs by reducing the rate of concrete deck deterioration, thereby delaying costly major rehabilitation and replacement activities caused by corrosion.

This scan will identify lessons learned from construction of bridge deck projects that utilize innovative materials and strategies. The information collected will allow States to consider future approaches to design bridge decks to provide better durability and service life for the decks of their structures.
