Abstract:The Texas Type T631 bridge rail was developed as a low-cost, flexible bridge rail system for TL-2
applications. Many of the features used for the system tested at MwRSF for TL-3 were incorporated into the
design developed for this project for MASH TL-2 application. The TxDOT Type T631 bridge rail was
designed, developed, and evaluated under MASH TL-2.
The objective of this research was to evaluate the impact performance of the new TxDOT Type T631
bridge rail to MASH TL-3. The TxDOT Type T631 bridge rail was intended to serve as a low-cost
replacement for the TxDOT Type T6 bridge rail for MASH TL-2 applications. The crash testing was
performed in accordance with the requirements of MASH TL-3.
The TxDOT T631 Bridge Rail performed acceptably for MASH TL-3.
