Designation:C1747/C1747M13Standard Test Method forDetermining Potential Resistance to Degradation ofPervious Concrete by Impact and Abrasion1This standard is issued under the fixed designation C1747/C1747M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers determining the potential resis-tance to degradation of pervious concrete by measuring themass loss of specimens subjected to combined action of impactand abrasion in a rotating steel drum.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in noncon-formance with the standard.1.3 The text of this test method references notes andfootnotes that provide explanatory information.These notesand footnotes(excluding those in tables)shall not be consid-ered as requirements of 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.(WarningFreshhydraulic cementitious mixtures are caustic and may causechemical burns to skin and tissue upon prolonged use.2)2.Referenced Documents2.1 ASTM Standards:3C125 Terminology Relating to Concrete and Concrete Ag-gregatesC131 Test Method for Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the LosAngeles MachineC136 Test Method for Sieve Analysis of Fine and CoarseAggregatesC172 Practice for Sampling Freshly Mixed ConcreteC192/C192M Practice for Making and Curing Concrete TestSpecimens in the LaboratoryC470/C470M Specification for Molds for Forming ConcreteTest Cylinders VerticallyC670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsC1688/C1688M Test Method for Density and Void Contentof Freshly Mixed Pervious ConcreteD6926 Practice for Preparation of Bituminous SpecimensUsing Marshall ApparatusE11 Specification for Woven Wire Test Sieve Cloth and TestSieves3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this test method,referto Terminology C125.3.2 Definitions of Terms Specific to This Standard:3.2.1 design density,nthe mass of a unit volume ofpervious concrete based on the theoretical mixture proportionsand void content and where the unit volume includes thevolume of the solids and the voids.3.2.2 raveling,nthe wearing away of a pavement surfacedue to dislodgement of aggregate particles.4.Summary of Test Method4.1 This test method consists of casting cylindrical speci-mens of pervious concrete at the design density,then subject-ing the cured specimens to a combination of actions includingimpact,abrasion or attrition,and grinding in a rotating steeldrum.The potential resistance to degradation by impact andabrasion is expressed as the percentage mass loss after 500revolutions of the steel drum.Higher potential resistance todegradation by impact and abrasion is associated with lowermass loss.5.Significance and Use5.1 This test method provides a procedure for evaluating thepotential resistance to degradation by impact and abrasion of1This test method is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregates and is the direct responsibility of SubcommitteeC09.49 on Pervious Concrete.Current edition approved Nov.1,2013.Published February 2012.Originallyapproved in 2011.Last previous edition approved in 2011 as C1747/C1747M11.DOI:10.1520/C1747_C1747M-13.2See Section on Safety Precautions,Manual of Aggregate and Concrete Testing,Annual Book of ASTM Standards,Vol.04.02.3For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 pervious concrete mixtures.A common failure mode of pervi-ous concrete pavements is raveling.This test allows thecomparison of the relative potential resistance to raveling ofpervious concrete mixtures of varying proportions and rawmaterials.In addition,in the field,raveling is caused byimproper paste consistency,workability loss,inadequatecompaction,and improper curingthis test method does notaddress any of these causes.There is no known correlationbetween this test method and the field performance of pervious
