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
