Product & Installation: ABSORB
®
350 Non-Redirective Gating Crash Cushion
Preface
ACP’s ABSORB
®
350 crash cushion system
is a water-filled, non-redirective, gating crash
cushion.
As with any roadside safety device, the
ABSORB
®
350 system must be installed properly
to ensure proper performance. Thoroughly review
and fully understand the instructions and product
limitations before starting the installation. Do not
start the installation without the proper plans and
tools required.
If you require additional information or have
questions about the ABSORB
®
350 Crash
Cushion System please call ACP on 02 8708
4400 or go to www.acprod.com.au
Introduction
The ABSORB
®
350 system has been tested
to meet the rigorous requirements of NCHRP
Report 350. The system attaches to permanent
and temporary steel and concrete barrier.
The ABSORB
®
350 system is a non-
redirective, gating crash cushion for narrow
hazard protection, with similar performance
characteristics to other non-redirective, gating
crash cushion systems. ABSORB
®
350 is easy to
install and requires no foundation or anchoring.
It is easy to maintain, and it restores in minutes
after impact.
Non-redirective, gating, crash cushions are
frequently used at locations where the vehicle
post impact trajectories can be accommodated
behind the system. If it is desirable to have the
majority of post impact vehicle trajectories on the
impact side of the system, a redirective, non-
gating crash cushion should be considered such
as a TAU II.
System Overview
The ABSORB
®
350 system is designed and
constructed to provide acceptable structural
adequacy, minimal occupant risk and safe
vehicle trajectory as set forth in NCHRP 350 for a
non-redirective, gating, crash cushion. Individual
sections of the system are linked and pinned
together to form a continuous freestanding
installation (i.e. the system is not anchored to the
foundation surface). The effective length of each
element is 1m and the effective overall height is
800 mm.
The effective width of the upright portion of each
section is 610mm. Each section is fabricated out
of a roto-molded shell that is filled with water and
fitted with steel hardware to allow the sections
to be connected. The mass of each section is
approximately 39kg empty and 317kg filled. Each
section takes 265L of water to fill.
