MASH Test 3-11 of the TxDOT Single Slope Bridge Rail (Type SSTR) on Pan-Formed Bridge Deck

摘要

The objective of this crash test was to determine whether the TxDOT Single Slope Traffic Rail (Type SSTR) would perform acceptably on a pan-formed deck when tested according to the guidelines set forth in Manual for Assessing Safety Hardware (MASH). The crash test performed was MASH test 3-11 involving a 2270P vehicle (5000-lb pickup truck) impacting the critical impact point (CIP) of the bridge rail at an impact speed and angle of 62 mi/h and 25 degrees, respectively. This report presents the details of the TxDOT Type SSTR on pan-formed bridge deck, description of the crash test performed, an assessment of the test results, and the implementation plan. The TxDOT Type SSTR bridge rail on pan-formed deck performed acceptably for MASH test 3-11.
