Flexural cracking behavior of reinforced UHPC overlay in composite bridge deck with orthotropic steel deck under static and fatigue loads

•Static and fatigue cracking behavior of R-UHPC overlay in UHPC-OSD systems are tested.•Cracking behavior of R-UHPC overlay in transverse and longitudinal directions are studied.•Nominal cracking strength of R-UHPC overlay of composite bridge decks is evaluated.•Fatigue resistance of R-UHPC overlay...
