Book Description
Precast bridge deck panels can be used in place of a cast-in-place concrete deck to reduce bridge closure times for deck replacements or new bridge construction. The panels are prefabricated at a precasting plant providing optimal casting and curing conditions, which should result in highly durable decks. Precast panels can be either full-depth or partial-depth. Partial-depth panels act as a stay-in-place form for a cast-in-place concrete topping. This study investigated only the behavior of full-depth precast panels. The research described in this report had two primary objectives. The first was to develop a performance specification for the grout that fills the haunch between the top of the beam and the bottom of the deck panel, as well as the horizontal shear connector pockets and the panel-to-panel joints. Tests were performed using standard or modified ASTM tests to determine basic material properties on eight types of grout. The grouts were also used in tests that approximated the conditions in a deck panel system. Based on these tests, requirements for shrinkage, compressive strength, and flow were established for the grouts. It was more difficult to establish a test method and an acceptable performance level for adhesion, an important property for the strength and durability of the deck panel system. The second objective was to quantify the horizontal shear strength of the connection between the deck panel and the beam prestressed concrete beams. This portion of the research also investigated innovative methods of creating the connection. Push-off tests were conducted using several types of grout and a variety of connections. These tests were used to develop equations for the horizontal shear strength of the details. Two promising alternate connections, the hidden pocket detail and the shear stud detail, were tested for constructibility and strength. The final outcome of this study a set of recommendations for the design, detailing, and construction of the connection between full-depth precast deck panels and prestressed concrete I-beams. If designed and constructed properly, the deck panel system is an excellent option when rapid bridge deck construction or replacement is required.

Book Description
The development of accelerated bridge construction (ABC) techniques and connection details has become a national research focus. With the aging of the interstate system and many bridges on key routes requiring extensive rehabilitation or replacement, the economic impact of construction time has become a key factor in the design of bridges. Several states have successfully standardized the ABC approach with high rates of public satisfaction. Compared to other ABC techniques, the technologies for pre-fabricated bridge decks are relatively mature. However, this technology has not been incorporated in Nevada. The goal of this research project is to develop design guidelines and specifications on the use of pre-fabricated bridge decks for Nevada based on existing techniques. A state-of-the-art literature review summarizing existing practices for the implementation of prefabricated deck panels was prepared. This information was used to assemble a survey that was sent to representatives of all state DOTs. The survey requested information from each DOT on their experience with prefabricated deck panels, connection details that were used, and the field performance of the panels and connections. Information from the literature review and survey was used to develop design specifications and recommendations for the Nevada Department of Transportation (NDOT). These specifications were supplemented with a design aid spreadsheet and finite element models to validate the provisions in the specifications and aid in the implementation of this technology. As part of this implementation, two design methods were developed: a simplified (design aid spreadsheet) method and a model based method. Survey results showed that full-depth prefabricated deck panels performed better and saved time compared to partial depth panels. Because of this, full-depth deck panels were the primary focus in this project. Results from the survey showed that guidelines and connection details developed by the Precast/Prestressed Concrete Institute (PCI) Northeast committee (PCI, 2011a) were widely used and led to satisfactory performance. These guidelines were used as the foundation for the proposed design specifications for NDOT. Information from the survey and literature review were used to supplement the PCI guidelines and add information specific to Nevada's needs. The guidelines were used to design full-depth deck panel systems for two existing bridges. The simplified and model based methods were applied to both design examples to determine whether the design specifications could be used to appropriately design full-depth deck systems for different cases. The results from the two design examples showed that the full-depth deck panel systems performed as expected and could be designed using the existing AASHTO and PCI provisions. Additional modeling beyond simple hand calculations was required for skewed and curved bridges. Based on these findings, prefabricated full-depth deck panels are recommended for use in ABC projects in Nevada using the assembled design specifications and design procedures created for this project.
