SECTION 530 REVETMENT SYSTEMS 5301 Description. Provide signed and sealed calculations of the block and cable sizing design for approval. Comply with the National Concrete Masonry Associations Design Manual for Articulating Concrete Block Revetment Systems, Second Edition, or the National Highway Design Manual for Articulating Concrete Block (ACB) Revetment Systems ii It is recommended that the designer analyze the project conditions and determine the ARTICULATING CONCRETE BLOCK FOR EROSION CONTROL TEK 119B Articulating Concrete Blocks (ACBs) (2014) the Design Manual for Articulating Concrete Block and ACB Design Spreadsheet (refs.
2, 8). ENVIRONMENTAL BENEFITS One of the environmental benefits of ACB erosion systems Design applications of articulated concrete blocks (ACB's). Acceptable factor of safety values with respect to application. ACB design procedure for hydraulic velocity and bed shear. Articulating concrete block (ACB) systems are used to provide protection to underlying soil materials. The term articulating implies the ability of the system to conform to changes in subgrade while remaining interlocked. ArmorFlex Design Manual ABRIDGED VERSION 2002 Design Manual for ArmorFlex Articulating Concrete Blocks.
Due to the mode of failure exhibited by articulating concrete block revetment systems, the Armorflex Design ManualAbridged Version 9 The basis for design shall be the publication Design Manual for Articulating Concrete Block Systems, Harris County Flood Control District (HCFCD). Critical Shear values for ACB systems shall be computed using the latest ASTM D7276 and D7277. Articulated Concrete Chute Design Ayres Associates preparing this" Design Manual for Articulating Concrete Block (ACB) Systems" (the" Manual" ).
DISCLAIMER This Design Manual provides guidelines and procedures for the design and installation of articulating concrete block revetment systems. Articulating concrete block Keywords: ACBs, articulating concrete block, design, factor of safety, erosion control, revetment FACTOR OF SAFETY METHOD Similar to many rip rap sizing methods, the Factor of Safety method quantifies hydraulic stability of ACB systems using a discrete particle approach (see ref.
