15. Supplementary Notes
Project performed in cooperation with the Texas Department of Transportation and the Federal Highway
Project Title: Roadside Safety Device Crash Testing Program
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.
