Performance of Cost-Effective Non-Proprietary UHPC in Thin Bonded Bridge Overlay

The use of Ultra High-Performance Concrete (UHPC) for thin bonded overlays for bridge deck rehabilitation has been successfully used in some pilot studies in Iowa, Delaware, and New York, and more extensively in Europe. Such innovative material can enable the construction of thin bonded overlays of 1 to 2 inch in thickness for the rehabilitation of bridge decks and restoration of the structural capacity of bridges. Despite encouraging results with some field applications, the high material unit cost of proprietary materials limits the wide acceptance of UHPC for bridge deck rehabilitation. The PI has developed a new class of cost-effective, non-proprietary UHPC mixtures that are self-consolidating to facilitate placement and finishing. The main objective of the proposed project is to evaluate the constructability and performance of non-proprietary thixotropic UHPC for thin bonded bridge deck overlay construction.
