Designation:D4867/D4867M09(Reapproved 2014)Standard Test Method forEffect of Moisture on Asphalt Concrete Paving Mixtures1This standard is issued under the fixed designation D4867/D4867M;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.Scope1.1 This test method covers procedures for preparing andtesting asphalt concrete specimens for the purpose of measur-ing the effect of water on the tensile strength of the pavingmixture.This test method is applicable to dense mixtures suchas those appearing in the Table for Composition of BituminousPaving Mixtures in Specification D3515.This test method canbe used to evaluate the effect of moisture with or withoutantistripping additives including liquids and pulverulent solidssuch as hydrated lime or portland cement.1.2 The values stated in either SI units or inch-pound unitsin parentheses shall be regarded separately as standard.Thevalues in each system may not be exact equivalents;therefore,each system must be used independently of the other,withoutcombining values in any way.1.3 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:2D979 Practice for Sampling Bituminous Paving MixturesD1074 Test Method for Compressive Strength of Bitumi-nous MixturesD1561 Practice for Preparation of Bituminous Mixture TestSpecimens by Means of California Kneading CompactorD2041 Test Method for Theoretical Maximum SpecificGravity and Density of Bituminous Paving MixturesD2726 Test Method for Bulk Specific Gravity and Densityof Non-Absorptive Compacted Bituminous MixturesD3203 Test Method for Percent Air Voids in CompactedDense and Open Bituminous Paving MixturesD3387 Test Method for Compaction and Shear Properties ofBituminous Mixtures by Means of the U.S.Corps ofEngineers Gyratory Testing Machine(GTM)D3496 Practice for Preparation of Bituminous MixtureSpecimens for Dynamic Modulus Testing(Withdrawn2010)3D3515 Specification for Hot-Mixed,Hot-Laid BituminousPaving Mixtures(Withdrawn 2009)3D3549 Test Method for Thickness or Height of CompactedBituminous Paving Mixture SpecimensD3665 Practice for Random Sampling of Construction Ma-terialsD4013 Practice for Preparation of Test Specimens of Bitu-minous Mixtures by Means of Gyratory Shear Compactor(Withdrawn 2013)3D4123 Test Method for Indirect Tension Test for ResilientModulus of Bituminous Mixtures(Withdrawn 2003)3D6926 Practice for Preparation of Bituminous SpecimensUsing Marshall Apparatus3.Summary of Test Method3.1 Potential for Moisture DamageThe degree of suscep-tibility to moisture damage is determined by preparing a set oflaboratory-compacted specimens conforming to the job-mixformula without an additive.The specimens are compacted toa void content corresponding to void levels expected in thefield,usually in the 6 to 8%range.The set is divided into twosubsets of approximately equal void content.One subset ismaintained dry while the other subset is partially saturated withwater and moisture conditioned.The tensile strength of eachsubset is determined by the tensile splitting test.The potentialfor moisture damage is indicated by the ratio of the tensilestrength of the wet subset to that of the dry subset.3.2 Additive EffectThe effect of an antistripping additiveis determined on a set of specimens containing an additiveprepared and tested as described in 3.1.The effect of anadditive dosage may be estimated by repeating the tests on setswith different additive dosages.3.3 Plant-Produced MixturesThe potential for moisturedamage or the effectiveness of an additive in a plant-produced1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.22 onEffect of Water and Other Elements on Asphalt Coated Aggregates.Current edition approved July 1,2014.Published November 2014.Originallyapproved in 1988.Last previous edition approved in 2009 as D4867/D4867M 09.DOI:10.1520/D4867_D4867M-09R14.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 mixture is determined on specimens that are laboratory com-pacted to expected field-level void content,divided into wetand dry subsets,and evaluated as
