• Abstract:
  Texas Department of Transportation (TxDOT) currently uses the TxDOT Type T101RC Bridge Rail, ; a steel post and beam bridge rail anchored to the top of concrete curbs. The T101RC Bridge Rail is ; 27 inches in height and can be anchored to the top of concrete curbs of varying heights. The heights of the ; posts and the number of bridge rail elements vary depending on the height of the concrete curb. The posts ; are anchored to the curb using four adhesive anchors. ; Based on crash testing of similar rail designs of the same height, the researchers believed that the ; TxDOT Type T101RC Bridge Rail would not meet the American Association of State Highway and ; Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) Test Level 3 (TL-3) ; criteria. The purpose of this portion of the project was to design and crash test a modified design of the ; TxDOT T101RC Bridge Rail that would meet the strength and safety performance criteria for TL-3 of ; MASH. A new bridge rail was developed and tested for this project. ; The TxDOT T131RC Bridge Rail met all the strength and safety performance criteria of MASH. This ; bridge rail is recommended for implementation on new or retrofit railing applications.
