Precast Concrete Barrier Crash Testing

摘要

The objectives of this project were to crash test the Oregon Standard (32-inch) F-shape precast concrete barrier and the Oregon Tall (42-inch) F-shape precast concrete barrier against the new NCHRP Report 350 standards, to ensure compliance of these safety systems. FHWA has required that such systems are acceptable under NCHRP standards by no later than October 2002. The results of the Test Level 3 crash tests showed that both barriers meet NCHRP requirements. Futhermore, FHWA acknowledged both barriers as having the best performance of any free-standing precast concrete barriers to date. The research report also discusses the performance of the Tall F-shape barrier in a Test Level 4 crash test, involving an 8,000 kg single-unit truck. The barrier passed this test as well.
