5.3 Site Grading
It is recommended that the area in advance of the
barrier be limited to a grading of 10H:1V and free
of undulations that may adversely affect the
trajectory of a dismounted rider.
5.4 Kerbs
Placing kerbs in front of the barrier is not
recommended. As an alternative subsurface grated
drainage should be considered.
5.5 Retrofitting
T he RiderPro mounting bracket connection to the
post just below the thrie beam with a 12mm hole
placed in the post allows for appropriate vertic al
align ment with of the MPR system with the w-
beam guardrail. This alignment reduces the
potential for rider snagging.
Attachment of
RiderPro
does not require any
dismantling or loosening of the existing guardrail
barrier and associated hardware . This reduces
installation time and avoids problems where debris
and/or vegetation can accumulate around the post.

5 Design Considerations.
5.1 Length Of Need.
The Beginning of the LON is placed at:
•
ACP Sentry Barrier ThrieB eam System
: at
the midspan between the 3 th and the 4 th
post from the RiderPro End Terminal .
5.2 Minimum installation Length:
The Minimum installation Length of the RiderPro is:
•
ACP Sentry Barrier ThrieB eam System :
20 meters (No 5 panels).
5.6 Placement within Guardrail End
Terminals
The end terminals of w-beam guardrail barriers are
designed to reduce the severity of a vehicle impact
near or at the end of the system.
These terminals may incorporate yielding posts,
energy-absorbing impact heads or a combination of
both.
It is recommended that
RiderPro
not be installed
within the guardrail end terminal section.

7 Minimum Horizontal Radius
(Installation curvature radius)
The RiderPro can achieve a minimum horizontal
radius curvature of 25m onsite installed onto the
Sentry Thrie Beam system , when supplied with
standard straight RiderPro panels. For installation
curvatures of less than 25m radius, pre-curved
RiderPro panels need to be ordered prior to
installation. Contact your
ACP
representative for
further information once the installation radius is
identified.
5.8 End Termination
A specifically designed end terminal is available for
attachment to the RiderPro .
It is a requirement that the
RiderPro
end terminal
is installed on both ends of the system.
