ABSTRACT:
The purpose of this research was to develop and evaluate a guardrail system to be placed with a 1H:1V slope. The structural capacity and the occupant risk factors of such proposed guardrail system were evaluated with respect to MASH TL-3 criteria. A W-beam guardrail system was tested under MASH TL 3-10 criteria, and based on the test result, more stiffness was desired.
The 1100C vehicle impacted the guardrail on 1H:1V slope 31.5 inches upstream of post 14 at an impact speed of 63.9 mi/h and an impact angle of 25.2 degrees. Due to rollover of the 1100C vehicle, the guardrail on 1H:1V slope did not perform acceptably for MASH Test 3-10 for longitudinal barriers.
