NCHRP Report 350 Test 3-11 of the Texas Type T411 Bridge Rail (0-1804-3)

The Texas Type T411 Bridge Rail is a concrete beam-and-posts system that was developed under a previous Texas Transportation Institute (TTI) study performed for Texas Department of Transportation (TxDOT). The Texas Type T411 was previously crash tested and approved under NCHRP Report 230 guidelines. However, with the adoption of NCHRP Report 350, the bridge rail needed to be reevaluated using the 2000-kg pickup truck. This report presents the details and results of the full-scale crash test on the Texas Type T411 Bridge Rail with the 2000-kg pickup truck traveling at 100 km/h and 25 degrees to evaluate performance at test level three.According to the specifications set for NCHRP Report 350 test designation 3-11, the Texas Type T411 Bridge Rail met all requirements except occupant risk. Significant occupant compartment deformation occurred on the center and right side of the vehicle. This deformation was judged to have the potential to cause serious injury.
