Abstract:

Two crash tests each were performed on a Thrie beam bridge rail and on the adjoining transition section to the approach guardrail. The bridge rail was designed (a) as a retrofit to replace the rail portion of an inadequate bridge rail supported on W6X15.5 steel posts at 6 ft 3-in. spacing, or (b) as a completely new barrier installed using resin capsule anchors to attach the posts to the edge of an existing bridge deck. The transition uses the same rail element, a 10-gauge Thrie beam, supported on standard wood posts. The tests performed approximated those required for a PL-1 bridge rail outlined in the 1989 American Association of State Highway and Transportation Officials' "Guide Specifications for Bridge Railings". The bridge rail was struck by a 5,400-lb pickup truck at 44.9 mph at an angle of 21 deg and a 1,830-lb car at 48.7 mph at an angle of 18 1/4 deg. The transition was hit by a 5,400-lb pickup truck at a speed of 44.7 mph at an angle of 18 deg and a 1,930-lb car at 49.1 mph at an angle of 20 3/4 deg. The crash tests satisfied the requirements for structural adequacy, occupant risk, and vehicle trajectory in National Cooperative Highway Research Program Report 230 as well as the evaluation criteria in the American Association of State Highway and Transportation Officials' guide specification.
