ABSTRACT
The objective of this research was to evaluate the impact performance of W-beam median barrier with rub rail according to the safety evaluation criteria of MASH Test Level 3 (TL-3). This evaluation involved performing two crash tests, one with an 1100C Small passenger car, and one with a 2270P pickup truck. The target impact speed and angle were 62 mi/h and 25 degrees for both tests.
This report provides details of the W-beam median barrier with rub rail detailed documentation of the crash tests and results, and an assessment of the performance of the median barrier for MASH TL-3 evaluation criteria.
The W-beam median barrier with rub rail performed acceptably for MASH TL-3 evaluation criteria for longitudinal barriers.
