Abstract: 
Concrete bridge deck deterioration is a leading cause for structurally deficient rating of bridges in the United States. To overcome this challenge, an innovative UHPC-NC composite deck panel with UHPC serving effectively as an overlay over normal concrete (NC) is proposed. The combination of UHPC and NC makes the proposed composite panel a durable and cost effective bridge deck solution. The influence of concrete strength and interface roughness on structural performance of the proposed composite bridge panel was investigated using a total of 60 slant shear tests and three flexural tests. The slant shear test results demonstrated that the bond strength of all five different interface textures was adequate, which was later confirmed by the flexural tests. Simple analytical models were developed to accurately predict the observed experimental behavior.
