MATT is a tangent, double-sided, redirective/gating and energy-absorbing attenuator/end terminal, for use with various longitudinal highway barriers in either unidirectional or bidirectional traffic applications – to include roadside, shoulder, median, and gore installations.
MATT is tested to MASH-2nd Edition (with 2020 Errata) Test Level 3 criteria and may be used in Test Level 1, Test Level 2, and Test Level 3 applications – when installed at the full Test Level 3 system length of 34′ 4-1/2″ [10.48 m].
During head-on impacts within MASH criteria, MATT is designed to dissipate energy by engaging the energy-absorbing technology of the device.
During length-of-need side impacts within MASH criteria, MATT is designed to contain and redirect the impacting vehicle.
*After an impact, the product must be inspected and evaluated per the direction of the specifying roadway authority. The ultimate decision on reparability rests with the specifying roadway authority and/or state DOT.
