High performance concrete(HPC)has broad prospects for its excellent mechanical properties and durability,and the most representative ones are ultra-high performance concrete(UHPC)and engineered cementitious composites(ECC).The combination of HPC and orthotropic steel bridge deck is a typical example of new material application in bridge engineering in recent years.The research progress about mechanical properties,fatigue properties,shear resistance and crack resistance in negative moment region of orthotropic steel-high performance concrete composite bridge decks are summarized and the specifications and standards of high performance concrete are summarized.Also,the problems and prospects in the emerging stage are put forward.These could provide a reference for the future research work and engineering application in related fields.
