Use of Ultra-High-Performance Concrete for Bridge Deck

2018-3-21  UHPC overlay can improve the performance of a bridge deck by providing resistance against moisture penetration and chloride ingress. With the developed overlay technology, UHPC can be applied as a thin layer on top of a concrete deck with a roughened surface, making it an attractive solution for bridge rehabilitation and new bridge construction.
