NCHRP 350 TL-2/3 Non Redirective, Bi-Directional Impact Attenuator The ABSORB 350 System is a non-redirective crash cushion that has been designed and tested to meet the rigorous requirements of NCHRP Report 350, Test Levels 2 (43 mph, 70 km/h) and 3 (62 mph, 100 km/h). This impact attenuator system offers maintenance workers and contractors a reliable and easy method to protect the ends of concrete barriers. The ABSORB 350 Crash Cushion can be attached to the end of permanent or portable concrete barrier (pcb) and steel barrier without the need to anchor the system to the roadway surface. At 24" [610 mm] wide, it is ideally suited for narrow areas where road and workspace is limited. ABSORB 350 is easy to install and is easier to restore after an impact than other non-redirective crash cushions because the system uses uniform modular components.

The ABSORB 350 Crash Cushion System is designed for use on narrow hazards (permanent, portable, and moveable concrete barrier ends) for exits, wide medians, edge of road locations and locations where other non-redirective or partially redirective systems are often used.

When maximum mobility is required, the ABSORB 350 System can be easily moved to a new lane position or to the side of the road using the optional wheeled lifting device.
