• Abstract:
  Precast concrete bridge rail systems offer several advantages over traditional cast-in-place rail designs, including reduced construction ; time and costs, installation in a wide range of environmental conditions, easier maintenance and repair, improved railing quality, and ; greater flexibility for aesthetic treatments. The objective of this project was to develop a precast concrete bridge rail system that met the ; TL-4 impact safety standards provided in MASH. The design criteria for the new bridge rail system included criteria for barrier geometry, ; provisions for open and closed rail options, constructability, weight limitations, segment length, design impact loads, connection of ; barrier segments, and connection to the bridge deck among other factors. ; The research effort proceeded in several phases. First, the research focused on determining the overall concept for the new bridge rail ; system in terms of the rail configuration and geometry as well as the required barrier reinforcement. Next, design concepts for the joints ; connecting adjacent rail segments were designed and subjected to dynamic component testing in order to select a design capable of ; meeting design criteria for the precast bridge rail system. After selection of an appropriate rail joint, the researchers developed connection ; details for the attachment of the rail to the bridge deck. Once the design of the various precast bridge rail components was completed, a ; complete set of CAD details for the prototype precast concrete bridge rail system were completed. Following the design effort, ; recommendations were made regarding the full-scale testing required to implement the new, precast concrete bridge rail system
