Abstract:

The objective of this research was to evaluate the impact performance of the TxDOT Type T222

Bridge Rail according to the Manual for Assessing Safety Hardware (MASH) TL-3. The crash testing was

performed in accordance with the requirements of MASH TL-3. This report describes the TxDOT T222

Bridge Rail, documents the performance of the rail system according to MASH TL-3 specifications, and

presents recommendations regarding implementation and future work.

The TxDOT T222 Bridge Rail contained and redirected the 2270P vehicle. The vehicle did not

penetrate, underride, or override the installation. Maximum dynamic deflection during the test was

2.1 inches. No detached elements, fragments, or other debris was present to penetrate or to show potential

for penetrating the occupant compartment, or to present hazard to others. Maximum occupant compartment

deformation was 4.0 inches in the kick panel area near the right front passenger’s feet. The 2270P vehicle

remained upright during and after the collision event. Maximum roll and pitch angles were 7 degrees and

12 degrees, respectively. Occupant risk factors were within the limits specified in MASH. The vehicle

exited within the exit box criteria. The TxDOT T222 Bridge Rail performed acceptably for MASH test 3-11.

This barrier is recommended for implementation on new construction, retrofit applications, and in temporary

applications in construction work zones.
