Investigation and Development of a MASH Test Level 6, Cost-Effective Barrier System for Containing Heavy Tractor Tank-Trailer Vehicles and Mitigating Catastrophic Crash Events – Phase V

Following the execution of a Manual for Assessing Safety Hardware (MASH) TL-6 full-scale crash test during the fourth year of this study, a suite of implementation details will be performed to aid state Departments of Transportation (DOTs) to implement the MASH Test Level 6 vehicle containment system into state DOT standard plans. It is anticipated that this barrier will prevent and/or mitigate the consequences of errant heavy tanker-truck vehicles striking opposing traffic on heavily-congested urban freeways and interstates as well as crashes into high-risk facilities or highly-populated areas, such as schools, malls, sports venues, concert arenas, military bases, international airports, or critical government buildings. Further augmentation of the design will be performed including footings for varying soil conditions and to accommodate underground facilities, design for accommodation for bridge sections, and optimization for barrier use in median and single-sided impacts (i.e., median and roadside versions). Load considerations on bridges and for attachments to adjacent features will be identified. Recommendations will be provided to accommodate tapered heights, barrier widths, and changes in barrier geometry outside of the critical length needed for TL-6.
