  • Abstract:
    The TxDOT T203 bridge rail is often used on bridges where asphalt overlays reduce the effective ; height of the bridge rail. This reduction in height due to asphalt paving overlay is undesirable. For this ; project, several geometric features were changed to improve the strength and crash performance of the T203 ; rail. These features include increasing the rail height to 32 inches, increasing the size and strength of the rail, ; and increasing the thickness of the post. In addition, the width of the post was reduced to 4 ft and the ; openings between the posts were increased to 6 ft. Orientation, placement, and frequency of reinforcing steel ; in the rail, post, and deck were also evaluated to determine if impact damage to the deck can be reduced. ; These proposed changes to the T203 rail led to the development of the TxDOT Type T223 bridge rail design, ; which is reported herein. ; The objective of this project was to evaluate the strength of the new TxDOT Type T223 Bridge Rail ; design with respect to different reinforcing steel details in the deck, rail, and posts. The strength of the new ; TxDOT Type T223 bridge rail was evaluated using dynamic bogie testing. These tests were performed at the ; ends/joint (two tests) and at mid-span locations (two tests). Reinforcing steel details varied at each test ; location to determine the preferred placement and orientation of reinforcing steel for the TxDOT Type T223 ; bridge rail and supporting deck to minimize deck damage during a design impact event.
