It is the responsibility of the contractor to establish and adopt appropriate safety and health practices, and comply with prevalent regulatory codes, such as OSHA (Occupational Health and Safety Administration) regulations. These guidelines do not purport to address the safety issues associated with installation of ACB revetment systems, including use of hazardous materials, mechanical equipment, and operations. 2) and comply with ASTM D6884, Standard of Practice for the Installation of Articulating Concrete Block (ACB) Revetment Systems (ref.

They are based on Design Manual for Articulating Concrete Block (ACB) Revetment Systems (ref. These guidelines apply to the installation of ACB revetment systems, whether hand-placed or placed as a mattress. Quality workmanship is important throughout the installation, including subgrade preparation, geotextile placement, block system placement, backfilling and finishing, and inspection. Proper installation of an ACB revetment system is essential to achieve suitable hydraulic performance and maintain stability against the erosive force of flowing water during the design hydrologic event. General information on ACB systems can be found in TEK 11-9B, Articulated Concrete Block for Erosion Control (ref.

The ACB system is a matrix of individual concrete blocks placed together to form an erosion-resistant revetment with or without a geotextile underlay for subsoil retention. Articulating concrete block (ACB) revetment systems are used to provide erosion protection.
