•Adding concrete overlay on the tensile face increased shear and flexural resistance.•Interface results with reinforcement properly anchored fit well with MC2010.•Ductile behaviour was achieved with reinforcement crossing the interface.•Reinforcement crossing the interface increased bond strength up...
