Abstract:The objective of this project was to complete the Manual for Assessing Safety Hardware (MASH) evaluation of the Wyoming box beam shoulder barrier by performing MASH Test 3-10. MASH Test 3-10 involves an 1100C vehicle impacting the barrier at a target impact speed and impact angle of 62 mi/h and 25°, respectively. This report provides details of the Wyoming box beam shoulder barrier, detailed documentation of the crash test results, and an assessment of the performance of the Wyoming box beam shoulder barrier for MASH Test 3-10 evaluation criteria. Additionally, the MASH compliance of the Wyoming box beam shoulder barrier is discussed. The Wyoming box beam shoulder barrier performed acceptably for MASH Test 3-10. The Wyoming box beam shoulder barrier performed acceptably for MASH Test 3-11 under National Cooperative Highway Research Program Project 22-14(03). Based on the successful outcome of both tests, it is concluded that the Wyoming box beam shoulder barrier is MASH compliant as a Test Level 3 longitudinal barrier.
