摘要: |
Crash testing for compliance with NCHRP Report 350 was performed on a Type 60K terminus. The Type 60K terminus was comprised of Type 60K portable concrete barrier (TL-3 approved) anchored to Type 60 concrete barrier at one end but free at the other. The Type 60K is a concrete barrier made up of 4-m long segments, which are connected together by pins. The barrier is freestanding and has a profile to match the Caltrans Type 60 median barrier. 9 segments (approximately 36 m) were pinned together with restraining stakes placed against the back edges of the last two segments of the barrier. For testing purposes, it was not necessary to anchor one end to Type 60 concrete barrier. One crash test was performed under Report 350 Test Level 3 with a 2000-kg pickup truck. The results of the test were within the limits of the Report 350 guidelines. The Type 60K Terminus is recommended for approval on California highways requiring a down-stream end treatment to the Type 60k barrier with the following limitations: First, there must be a need to be able to remove the barrier. Second, because a blunt end is exposed, it may not used in locations where a reverse hit is possible. Third, because it is restrained from lateral movement in one direction only, it can not be placed where impact can occur on the unrestrained side. / Supplementary Notes: This project was performed in cooperation with the U.S. Department of Transportation, Federal Highway Administration, under the research project titled 'Compliance Crash Testing of the Type 60K Terminus.'.
