Use of Ultra-High-Performance Concrete for Bridge Deck Overlays
The Iowa Department of Transportation has released a report that discusses the implementation of a new ultra-high-performance concrete (UHPC) mix to accommodate surface crowning on bridge decks. UHPC has a higher tensile strength and low permeability than normal concrete, which has the potential to minimize cracking and water and chloride ingression, which in turn may extend the lifespan of the bridge.
