Abstract
While concrete decks are often used in bridge structures because of their strength and durability, exposure to heavy traffic loads and environmental stressors can cause cracks to form in the concrete. Adding fibers to the concrete mix can strengthen it and mitigate the risk of cracking, not only during curing but also after the bridge is in service. Researchers identified the optimal types and amounts of fibers to add to enhance crack resistance and extend the service lives of Iowa bridges.
