DEFINITIONS
1.2.1
Articulating Concrete Block (ACB) Revetment System
A matrix of interconnected concrete block units for erosion protection.
Units are connected by geometric interlock and/or cables, geotextiles, or
geogrids, and typically include a geotextile underlayment for subsoil
retention.
1.2.2
Blocks
Articulating concrete block revetment units will be referred to as blocks.
1.2.3
Interlocking Blocks
Each pair of abutting blocks shall have interlocking keys that limit
lateral expansion. The key and keyhole shall have an interference fit such
that the joint movement has a minimum aperture at closure, and a maximum
aperture when pulled apart. The joint freeplay shall allow articulation of
each individual block.
1.2.4
Freeplay
Freeplay shall be the maximum lateral joint movement for interlocking
blocks (difference between maximum and minimum aperture).
