The objective of this study was to crash test and evaluate these transitions according to requirements of NCHRP Report 350. The scope of this study is as follows: "This study will crash test a series of thrie beam transitions from guardrails to bridge rails in accordance with the appropriate test levels of National Cooperative Highway Research Program (NCHRP) Report 350. These transition designs were selected by the State representatives for State Planning and Research (SP&R) Pooled Fund Study No. 2-134, "Testing New Bridge Rail and Transition Designs." The following transitions were tested under this project: Ohio Nonsymmetrical Type 2 W-beam to Thrie Beam Transition.

The purpose of the tests reported herein was to assess the performance of the 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition according to the safety-performance evaluation guidelines included in AASHTO MASH. The crash tests were performed in accordance with MASH TL-3, which involves two full-scale crash tests (MASH Tests 3-20 and 3-21). However, MASH states that when there are transitions between two barrier types with different stiffness, one from a more flexible barrier and the other to a more rigid barrier, a full-scale crash test is recommended for both types. Therefore, MASH Test 3-21 was performed at the transition from the thrie beam rail to bridge rail, and at the transition from the W-beam rail to thrie beam rail. This report provides details of the 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition, detailed documentation of the crash tests and results, and an assessment of the performance of the 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition for MASH TL-3 transition evaluation criteria. The 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition performed acceptably for MASH TL-3 transitions.
