Significance and Use
5.1 An articulating concrete block system is comprised of a matrix of individual concrete blocks placed together to form an erosion-resistant system with specific hydraulic performance characteristics. These systems in practice are commonly referred to as ACB revetment systems. The system includes a filter layer compatible with the subsoil, which allows infiltration and exfiltration to occur while providing particle retention. The filter layer may be comprised of a geotextile, properly-graded granular media, or both. The blocks within the matrix shall be dense and durable, and the matrix shall be flexible and porous.
5.2 This standard is intended to outline the requirements for the preparation, installation, and inspection of the components of the articulating concrete block system.
5.3 This standard is intended for use by designers, contractors, and inspectors 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.
Scope
1.1 The purpose of this standard is to provide recommended guidelines for the proper installation and inspection 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.
1.3.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The slug unit is not given, unless dynamic (F = ma) calculations are involved.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
