• Abstract:
  A full-scale crash test was performed to evaluate the impact performance of a Texas T223 concrete ; beam and post bridge rail anchored to a 5-inch cast-in-place deck (CIPD). The testing followed the MASH ; standards for Test Level 3 (TL-3) longitudinal barriers. The test performed was American Association of ; State Highways and Transportation Officials (AAHSTO) Manual for Assessing Safety Hardware (MASH) ; test 3-11, which involves a 2270P (5000 lb) pickup truck impacting the critical impact point (CIP) of the ; barrier at a nominal impact speed and angle of 62 mi/h and 25 degrees, respectively. This test evaluated the ; strength of the barrier and its anchorage to the 5-inch CIPD. ; The T223 bridge rail anchored to a 5-inch CIPD successfully met all required MASH evaluation ; criteria. The rail anchorage withstood the design impact without any visible distress. The rail anchorage ; detail is considered suitable for implementation when concrete bridge rails are attached to 5-inch decks cast ; on prestressed box and slab beams. The anchorage detail is considered acceptable for use with the T223 ; bridge rail, other concrete bridge rails, and metal rails mounted on concrete parapets.
