strength shall include appropriate factors of safety, with particular
attention given to the grab points.
2.3.3
Design Requirements for Cable
**************************************************************************
NOTE: The designer may need to research
survivability of cables in the environment where the
ACB will be placed. The installation requirements
for cable strength usually govern, unless anchors
are used.
**************************************************************************
ACB's that rely on cables to maintain block to block interconnection shall
use ropes manufactured from polyester, stainless steel wire, or galvanized
steel wire. The cable shall have a minimum breaking strength of [_____]
pounds. Polyester rope shall be constructed of high tenacity, low
elongating, continuous filament polyester fibers; and shall consist of a
core construction comprised of parallel fibers contained within an outer
jacket or cover.
2.3.4
Anchors
**************************************************************************
NOTE: Anchors require a cabled system. Anchors
should be used with caution. Control of mattress
uplift may only be successful for short term, low
frequency, overload. ACB mattresses that are
locally uplifted, with or without anchors, may show
significant subgrade distortion, which could be a
precursor to failure. Anchors spaced throughout the
revetment also require special details to maintain
integrity of the geotextile filter.
Because anchors are not required for typical
installations, this paragraph may commonly be
deleted. Where anchors are used for specialized
applications, add requirements for anchor materials,
minimum property requirements, and design
characteristics.
Drawings must detail location and spacing of anchors.
**************************************************************************
Anchors shall be selected with an ultimate vertical pullout resistance for
the project site soil conditions of at least [_____] pounds. Anchors shall
be capable of being attached directly to the articulating concrete block
mat in a manner which will achieve little or no slack in the cable system
or gaps in the articulating concrete block mattress. Anchors shall be
attached to the mat in such a manner that they will not be affected by
tampering or vandalism. Anchors shall have the capability of being
load-tested to the specified pull-out capacity.
