Book Description
This report describes a full-size field demonstration of a rapid bridge deck replacement concept put forward several years ago. The concept was to utilize a sand mortar made with a rapid setting epoxy to provide the shear tie between precast concrete deck panels and existing steel stringer beams. The demonstration site was a 50 ft simple span that serves as part of the SPUR 326 overpass over the AT & SF railroad tracks in downtown Lubbock, Texas. The demonstration bridge is one of two identical bridges, side-by-side; the other was redecked using a conventional poured-in-place technique. Eight precast panels, each 6 ft 3 in. x 45 ft x 8 in., were used to form the experimental deck. Each panel was cast with blockouts (holes) positioned directly over the supporting steel beams. When the original concrete deck was removed, the steel shear studs were cut away leaving the top of the flanges of the steel beams clean and flat. The precast panels were then positioned atop of the steel in an operation lasting less than 5 hours, the new steel studs were welded into place through the blockouts in about 4 hours, and then the panels were epoxied into place in less than 2 full working days.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Report 324: Prefabricated Bridge Elements and Systems to Limit Traffic Disruption During Construction assesses and documents the use of innovative prefabricated elements and systems and assesses its effects on on-site construction time and cost, closure time, and environmental impacts. The synthesis report also looks at the use of fiber-reinforced polymers and other advanced materials and new technologies that are gaining in popularity but are still in the experimental stages.

Book Description
A literature review concerning the objectives of the project was completed. A significant number of published papers, reports, etc., were examined to determine the effectiveness of full depth precast panels for bridge deck replacement. A detailed description of the experimental methodology was developed which includes design and fabrication of the panels and assembly of the bridge. The design and construction process was carried out in cooperation with the project Technical Review Panel. The major components of the bridge deck system were investigated. This includes the transverse joints and the different materials within the joint as well as composite action. The materials investigated within the joint were polymer concrete, non-shrink grout, and set-45 for the transverse joint. The transverse joints were subjected to direct shear tests, direct tension tests, and flexure tests. These tests exhibited the excellent behavior of the system in terms of strength and failure modes. Shear key tests were also conducted. The shear connection study focused on investigating the composite behavior of the system based on varying the number of shear studs within a respective pocket as well as varying the number of pockets within a respective panel. The results indicated that this shear connection is extremely efficient in rendering the system under full composite action. Finite element analysis was conducted to determine the behavior of the shear connection prior to initiation of the actual full scale tests. In addition, finite element analysis was also performed with respect to the transverse joint tests in an effort to determine the behavior of the joints prior to actual testing. The most significant phase of the project was testing a full-scale model. The bridge was assembled in accordance with the procedures developed as part of the study on full-depth precast panels and the results obtained through this research. The system proved its effectiveness in withstanding the applied loading that exceeded eight times the truck loading in addition to the maximum negative and positive moment application. Only hairline cracking was observed in the deck at the maximum applied load. Of most significance was the fact that full composite action was achieved between the precast panels and the steel supporting system, and the exceptional performance of the transverse joint between adjacent panels.
