SYNTHETIC FIBER-REINFORCED CONCRETE BRIDGE DECKS: REDEFINING BRIDGE DECK DESIGN AND BEHAVIOR
Researchers at the Technical University of Nova Scotia have pioneered the development of concrete slab on girder bridge decks totally devoid of all internal steel reinforcement. The decks are constructed of synthetic fiber-reinforced concrete on composite steel girders restrained by external steel straps. The discrete reinforcing fiber used is a collated fibrillated polypropylene fiber. The major benefit of this approach is the reduction of long-term maintenance costs and the increase in bridge deck lifespan. An overview of the concepts behind this technology, theoretical and experimental work that has been undertaken, and some of the practical aspects of designing a fiber-reinforced concrete mix with high volume fractions of synthetic fiber are presented.
