The purpose of the tests reported herein was to assess the performance of the Texas Department of Transportation's (TxDOT's) shallow anchorage single slope traffic rail (SSTR) 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). MASH Test 4-12 was performed on the TxDOT shallow anchorage SSTR to determine the structural adequacy of the anchorage. Two different barrier configurations were evaluated: with and without dowel bars between barrier segments across expansion joints. This report provides details of the TxDOT shallow anchorage SSTR, the crash tests and results, and the performance assessment of the TxDOT shallow anchorage SSTR as a MASH Test Level 4 (TL-4) longitudinal barrier. Both variations of the TxDOT shallow anchorage SSTR (with and without dowel bars between barrier segments across expansion joints) were determined to be MASH TL-4 compliant. No delamination or damage to the deck was observed in the test installation after impact
