(Practice)Standard Practice for Installation of Articulating Concrete Block (ACB) Revetment Systems (Withdrawn 2024)
Standard Practice for Installation of Articulating Concrete Block (ACB) Revetment Systems (Withdrawn 2024)
SIGNIFICANCE AND USE
5.1 This standard is intended for use by designers and contractors to assist in understanding the importance of proper installation of articulating concrete block revetment systems in order to achieve suitable hydraulic performance and maintain stability against the erosive force of flowing water.
5.2 An articulating concrete block system is comprised of a matrix of individual concrete blocks placed together to form an erosion-resistant overlay with specific hydraulic performance characteristics. The system includes a geotextile underlay compatible with the subsoil that allows hydraulic infiltration and exfiltration to occur while providing particle retention. The blocks within the matrix shall be dense and durable and the matrix shall be flexible and porous.
5.3 Articulating concrete block systems are used to provide erosion protection to underlying soil materials from the forces of flowing water. The term “articulating,” as used in this standard, implies the ability of individual blocks of the system to conform to changes in the subgrade while remaining interconnected by virtue of block interlock and/or additional system components such as cables, ropes, geotextiles, or geogrids.
5.4 The definition of articulating concrete block systems does not distinguish between interlocking and non-interlocking block geometries, between cable-tied and non-cable-tied systems, between vegetated and non-vegetated systems or between methods of manufacturing or placement. Furthermore, the definition does not restrict or limit the block size, shape, strength, or longevity; however, guidelines and recommendations regarding these factors are incorporated into this standard. This standard does not specify size restrictions for individual block units. Block systems are available in either open-cell or closed-cell varieties.
5.5 The installation of articulated concrete block systems shall be performed so as to maintain intimate contact between the blocks, the geotextile filte...
SCOPE
1.1 The purpose of this standard is to provide recommended guidelines for the proper installation of articulating concrete block (ACB) revetment systems.
1.2 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace standard of care by which adequacy of a given professional service must be judged, nor should this document be applied without considerations of a project's many unique aspects. The word “standard” in the title of this document means only that the document has been approved through the ASTM consensus process.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Use of units other than inch-pound shall not be considered non-conformance with this practice as long as the selected parameters are met as a minimum.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
The purpose of this standard is to provide recommended guidelines for the proper installation of articulating concrete block (ACB) revetment systems.
Formerly under the jurisdiction of Committee D18 on Soil and Rock, this practice was withdrawn in January 2024 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards s...
