The CushionWall II System is a unique solution for high-frequency
lateral impact areas, such as severe highway curves. This energy
absorbing, longitudinal wall gradually dissipates the kinetic energy
of an errant vehicle during a lateral impact, and safely redirects
it back onto the roadway at a shallow angle. This cushioning reduces
the severity of the impact and helps the driver maintain control
of the vehicle, which reduces the risk of secondary accidents. The
CushionWall II System consists of a series of interconnected “smart
plastic” cylinders that can be customized to fit each specific
application. The series of cylinders fits behind a concrete transition
from the hazard. During an impact, the reusable “smart plastic”
cylinders compress to maximize energy absorption. These “smart
plastic” cylinders are made from high molecular weight, high
density polyethylene (HMW/HDPE). After a design lateral impact,
the cylinders regain a high percentage of their original shape without
maintenance or repair.
Superior Crash Cushion Design
design consists of energy-absorbing, reusable, "smart plastic"
(HMW/HDPE) cylinders that fit behind a concrete transition. The
cylinders can be customized to fit each specific application.
Energy-absorbing, longitudinal wall dissipates kinetic energy, and
redirects the vehicle back onto roadway at shallow angle. The cushioning
keeps driver in control, reducing secondary accidents.
at speeds up to 70 km/h (43 mph) and at angles as high as 20°,
when impacted by vehicles weighing up to 2041 kg (4500 lb).
No expendable components need to be refilled or replaced. 99% Self-Restoring
after design impacts.
The CushionWall® II system will self restore after most design
impacts, typically regaining up to 99% of its original shape and
capacity without maintenance or repair of major components.
