"Joints are often considered as the weak link in a structure and often deterioration of the structure initiates from the joints. Joints transfer the stresses from super-structure to sub-structure and in this process are subjected to large transfer stresses. Not much attention is given to the design of joints as they are positioned in low moment regions and typically a 4 to 6 ksi (28 to 41 MPa) concrete is used to fill the joints. One of the solution to this problem is Ultra-high performance concrete (UHPC). In the recent past significant research has been done to use UHPC in deck-level connections and successful results were obtained. UHPC is a relatively new concrete material which not only has high compressive (18 ksi/124 MPa) and tensile strengths (5 ksi/35 MPa) with a very high chemical resistance, and durability. Use of steel fibers in UHPC helps increasing the service life. UHPC was successfully used by New York State and Iowa State Department of Transportations (DoT) in many bridges as various components, and proved to help with Accelerated Bridge Construction (ABC) which makes its use economical and time saving.

This research focused on using UHPC as joint filler material along with High strength self-consolidating concrete (HS-SCC) while studying the effects of using different continuity details and effects of surface preparation of beam in a reinforced concrete section subjected to high-moment loading using 22 test specimens. An investigation of non-prestressed Missouri Department of Transportation (MoDoT) end girder detail using UHPC in the joint was also conducted. UHPC when used in the joints can be a viable solution making joints the stronger link holding the structure together"--Abstract, page iii.
