Project 3.18: Steel-Free Concrete Bridge Decks

Steel-Free Concrete Bridge Decks

Project 3.18:

Project Summary

In order to realize a potentially transformational improvement in concrete bridge deck durability, the proposed research program intends to validate a deck design by which little to no conventional reinforcement is required. The design relies on the development of so-called arching action to maintain compressive stresses in the concrete thereby minimizing the risk of cracks that adversely affect long term durability. The project will move the technology forward by both validating the structural parameters by which the arching action is invoked, and by developing a suitable concrete mix reinforced with small non-metallic fibers that will meet the structural and long-term durability requirements. The outcome of the project will be a set of guidelines by which a field demonstration project can be developed.
