CRASH Test: 80000 lb tractor trailer 50 mph at 15 degrees into barrier

  • The last test of a roadside barrier's ability to contain a runaway tractor-tanker fully loaded to 80,000 pounds took place in Texas more than three decades ago.

    Since then, the Manual for Assessing Safety Hardware, yes MASH, Test Level 6 standard called for concrete barriers 90 inches tall to capture and contain a tanker truck traveling at highway speeds.

    On Wednesday, researchers at the University of Nebraska-Lincoln's Midwest Roadside Safety Facility proved a shorter, thinner barrier could match the larger one's performance, potentially resulting in the first change to the national standard in several decades.
    The barrier’s performance capturing a vehicle that collided with it an angle of 15 degrees traveling 50 mph -- an uncommon combination in most crashes -- indicates it would be successful at other speeds and angles as well, Stolle added.
    The tank was filled with 7,000 gallons of water attached to a 2010 Freightliner Columbia and speeding it directly into the barrier
We look forward to seeing the full report once posted to the Research Publication link for University of Nebraska-Lincoln's Midwest Roadside Safety Facility
