An innovative steel and concrete composite bridge deck slab using bent bars and epoxy as shear connectors was proposed. Four slab specimens with di erent types of concrete were fabricated and tested to study the load capacities of positive and negative moment regions of the slabs. e cracking and ultimate loads of the specimens were recorded and compared with the results calculated through the reinforced concrete theory and with the design load of the bridge deck slab. It was found that reinforced concrete theory can generally be applied for the proposed slab as well. e e ectiveness of the shear connector design of the proposed slab was validated. Meanwhile, the unfavourable e ect of the haunch on the shear capacities of the positive moment region of steel and concrete composite bridge deck slab was observed.
