description Ultra high performance concrete (UHPC) is a cementitious composite material that widely accepted nowadays due to its superior mechanical properties, low permeability and long term durability. The exceptional mechanical properties of UHPC make it a good candidate to be used in the construction of new bridges or rehabilitation of existing bridges especially to connect the precast component together. UHPC experiences superior compressive and tensile strengths, exceptional bond strength, negligible permeability, and minimal creep or long-term shrinkage. The study examined the performance of precast concrete components connected using UHPC wet joints under flexure and shear load protocols. The examined variables are type of precast components, UHPC wet joint geometry, reinforcement details, and the effect of the UHPC overlay. Two types of UHPC wet joint were considered in the current study. The precast concrete made of high strength concrete (HSC) interface was prepared using exposed aggregate surface preparation while the precast UHPC components interface was prepared using fiber exposure. The results demonstrated the wet joint shape and reinforcement had a significant effect on the load capacity under both flexural and shear load. Furthermore, adding the UHPC overlay improved the joint performance and increased the load capacity.
