What is a Barrier?
By definition, a barrier is designed to provide positive protection, containing and redirecting an impacting vehicle.
In order to be designated a barrier and be certified for use on a job
site, a device must pass NCHRP-350 crash test requirements and the
manufacturer must be issued a federal acceptance letter
(and be able to produce it on request). Barriers are required to
prevent an impacting vehicle from penetrating the barrier line at test
level speeds, and at the TL3 level, our MB350 had a deflection of just
11 feet.
Water-filled
barriers are set up in three one-thousand foot sections in the Houston,
TX area, replacing the concrete median. In the event of an evacuation,
the plastic barriers can be emptied and quickly moved to allow traffic
to use all lanes.

requirements
To be used as a barrier, the MB350 must be used with the steel bar kit.
The kit provides additional strength and keeps vehicles from
penetrating the barrier line.

The
minimum length of need (LON) for NCHRP-350 compliance is 33
interconnected barriers, or 198.5 ft. Each barrier must be ballasted to
capacity with an approximate weight of 1666 lbs. |

Accessories
The MB350 can also be used in situations where barriers are not
required, such as surrounding job sites where traffic is not a
consideration. The MB350 may be sold with a corner connector that allows setup to form a corner to form a rectangular perimeter.
It
can also be used with fence panels, which can be fitted with chain link
fence to surround job sites and reduce passerby visibility. However,
the fence is not NCHRP-350 compliant for use on roadway construction.
Our portable water barrier makes many jobs safer and easier to manage. |
