ABSTRACT
The purpose of the tests reported herein was to design, simulate, and access the performance of a guardrail system on a 1H: 1V slope, according to the safety performance evaluation guidelines included in the second edition of the American Association of State Highway and Transportation Officials (AASHTO) manual for assessing safety hardware (MASH). The crash test were performed in accordance with MASH test level-3 (TL-3):
MASH Test 3-10: An 1100C vehicle weighting 2,420 lb impacting the longitudinal barrier while traveling at 62 mi/h and 25 degrees.
MASH Test 3-11: An 2270P vehicle weighting 5,000 lb impacting the longitudinal barrier while traveling at 62 mi/h and 25 degrees.
The report provides development history and details of the Guardrail System on 1H:1V Slope, the crash tests and results, and the performance assessment of the Guardrail System on 1:1 Slope for MASH TL-3 Longitudinal Barrier evaluation criteria.
The Guardrail System on 1:1 slope met the performance criteria for MASH TL-3 Longitudinal Barrier.
