| Abstract: | The purpose of the tests reported herein was to assess the performance of prioritized attachments to concrete barrier systems according to the safety-performance evaluation guidelines included in the American Association of State Highway and Transportation Officials Manual for Assessing Safety Hardware (MASH), Second Edition. The crash tests for the attachments on the single-slope concrete median barrier were performed in accordance with MASH Test Level 4 (TL-4), and the crash tests for the attachments on the F-shape concrete median barrier were performed in accordance with MASH Test Level 3 (TL-3). This report provides details on the prioritized attachments to concrete barrier systems, the crash tests and results, and the performance assessment of the investigated systems for MASH TL-3 and TL-4 longitudinal barrier evaluation criteria. The investigated systems met the performance criteria for MASH TL-3 (F-shape) and TL-4 (single-slope) longitudinal barriers. |
