When renovating upgrading and enhancing reinforced concrete bridge deck surfaces design consultants often choose an asphalt concrete cover. There are many factors affecting the quality of a composite structure in which the upper layer is an asphalt concrete cover and the lower layer is a Portland cement concrete such as the quality of the asphalt concrete layer AC and the between the upper and lower layers. The strength of the adhesion layer between the two layers depends on the surface characteristics of the bridge s concrete slab and the type and proportion of the adhesive material. This article presents experimental results of the strength of the adhesion layer between a concrete layer and an ultra-high- performance concrete UHPC layer using the flat shear and tensile test model. Three types of adhesion materials namely Nova bond asphalt emulsion CRS-1P Polymer emulsion and Hyper Primer adhesive were selected for the research. The experimental results allow engineers to choose an appropriate type and ratio of adhesives for similar composite structures.
