• Description:
  This TechNote introduces ultra-high performance concrete (UHPC) as a potential solution for bridge deck overlays. A brief review of the history and development of UHPC is presented, followed by a summary of the properties that make UHPC a viable overlay solution. A laboratory investigation on the tensile bond strength of a UHPC specially formulated for overlay applications is then presented. This investigation provides a comparison between UHPC and latex-modified concrete (LMC) overlays using different substrate materials and surface preparations. Lastly, this TechNote highlights the findings of a field study and subsequent laboratory investigation aimed at evaluating the bond between a recently installed UHPC overlay and the existing reinforced concrete bridge deck. The full details and findings of this field study are available in a report by Haber et al. (2017).
