Standard Specification for Materials and Manufacture of Articulating Concrete Block (ACB) Systems
STANDARD published on 1.12.2018
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the standard materials composition, physical properties, structural components, manufacturing methods, and testing requirements for articulating concrete block reventment systems for use in erosion protection to underlying soil materials from flowing water forces. Articulating concrete blocks may be produced at a block plant or onsite using either wet-cast or dry-cast production techniques. Reventment cable and fittings shall be designed in such a manner as to provide adequate strength and durability characteristics to facilitate safe lifting and placing of large mattresses. The materials shall consist of aggregates and cementitious materials which shall be Portland, blended, hydrated lime, or pozzolan cements and shall conform to the physical requirements such as compressive strength, water absorption, density or unit weight, and freeze-thaw durability. The system includes a geotextile filter which shall comply to grab strength, sewn seam strength, tear strength, puncture strength, and elongation requirements. Geotextile-subsoil compatibility assessment shall include functional requirements for permeability, particle retention, and resistance to clogging. Physical property requirements for permittivity, aperture size, percent open area, and UV stability shall be based on site-specific soil characteristics, site conditions, and construction techniques.
