MASH Test 4-12 on T2P Retrofit Bridge Rail

The purpose of the test reported herein was to assess the performance of a retrofit rail for the Texas Department of Transportation (TxDOT) T2P bridge rail according to the safety-performance evaluation guidelines included in the American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH). The crash test was performed in accordance with MASH Test 4-12, which involves a 10000S vehicle weighing 22,000 lb impacting the retrofit bridge rail while traveling at a nominal impact speed and angle of 56 mi/h and 15 degrees. This report provides details on the TxDOT T2P retrofit bridge rail, the crash test and results, and the performance assessment of the TxDOT T2P retrofit bridge rail for MASH Test 4-12 longitudinal barrier evaluation criteria. The TxDOT T2P retrofit bridge rail met the performance criteria for MASH Test 4-12 for longitudinal barriers.
