Designation:D727616Standard Guide forAnalysis and Interpretation of Test Data for ArticulatingConcrete Block(ACB)Revetment Systems in Open ChannelFlow1This standard is issued under the fixed designation D7276;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 The purpose of this guide is to provide recommendedguidelines for the analysis and interpretation of hydraulic testdata for articulating concrete block(ACB)revetment systemsunder steep slope,high velocity flow conditions in a rectangu-lar open channel.Data from tests performed under controlledlaboratory conditions are used to quantify stability perfor-mance of ACB systems under hydraulic loading.This guide isintended to be used in conjunction with Test Method D7277.1.2 This guide offers an organized collection of informationor a series of options and does not recommend a specific courseof action.This document cannot replace education or experi-ence and should be used in conjunction with professionaljudgment.Not all aspects of this guide may be applicable in allcircumstances.This ASTM standard is not intended to repre-sent or replace the standard of care by which adequacy of agiven professional service must be judged,nor can thisdocument be applied without considerations of a projectsmany unique aspects.The word“Standard”in the title of thisdocument means only that the document has been approvedthrough the ASTM consensus process.1.3 The values stated in inch-pound units are to be regardedas standard.The user of the standard is responsible for any andall conversions to other systems of units.Reporting of testresults in units other than inch-pound shall not be regarded asnonconformance with this test method.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD6026 Practice for Using Significant Digits in GeotechnicalDataD6684 Specification for Materials and Manufacture of Ar-ticulating Concrete Block(ACB)Revetment SystemsD6884 Practice for Installation of Articulating ConcreteBlock(ACB)Revetment SystemsD7277 Test Method for Performance Testing of ArticulatingConcrete Block(ACB)Revetment Systems for HydraulicStability in Open Channel Flow3.Terminology3.1 For definitions of common terms used in this standard,see Terminology D653.4.Summary of Guide4.1 The analysis and interpretation of data from hydraulictests of articulating concrete block(ACB)revetment systems isessential to the selection and design of a suitable system for aspecific application.This guide provides guidelines for assist-ing designers and specifiers in developing a correspondencebetween the test data and the stability parameters used fordesign.4.2 This standard addresses the analysis of hydraulic testdata that is generated from a test or series of tests conducted inaccordance with Test Method D7277.5.Significance and Use5.1 This standard is intended for use by researchers anddesigners to assess the stability of articulating concrete block(ACB)revetment systems in order to achieve stable hydraulicperformance under the erosive force of flowing water.1This guide is under the jurisdiction ofASTM Committee D18 on Soil and Rockand is the direct responsibility of Subcommittee D18.25 on Erosion and SedimentControl Technology.Current edition approved April 1,2016.Published April 2016.Originallyapproved in 2008.Last previous edition approved in 2008 as D7276-08.DOI:10.1520/D7276-16.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 An articulating concrete block system is comprised of amatrix of individual concrete blocks placed together to form anerosion-resistant revetment with specific hydraulic perfor-mance characteristics.The system includes a filter layercompatible with the subsoil which allows infiltration andexfiltration to occur while providing particle retention.Thefilter layer may be comprised of a geotextile,properly gradedgranular media,or both.The blocks within the matrix shall bedense and durable,and the matrix shall be flexible and porous.5.3 Articulating concrete block systems are used to provideerosion protection to underlying soil materials from the forcesof flowing water.The term“articulating,”as used in thisstandard,
