Designation:C109713Standard Specification forHydrated Lime for Use in Asphalt Cement or BituminousPaving Mixtures1This standard is issued under the fixed designation C1097;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 This specification covers high calcium,dolomitic andmagnesian-hydrated lime for use in asphalt cement or bitumi-nous paving mixtures.NOTE1Hydrated lime,either calcitic,dolomitic,or magnesian,improves bonding of bitumen and aggregates which reduces susceptibilityto moisture damage,reduces age hardening by chemically stabilizingpolar compounds found in asphalts,and increases initial stiffness ofasphalt mixtures.NOTE2No attempt is made to present requirements for any by-product lime.1.2 This standard does not purport to address the safetyconcerns associated with its use.It is the responsibility of theuser of this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2C25 Test Methods for Chemical Analysis of Limestone,Quicklime,and Hydrated LimeC50 Practice for Sampling,Sample Preparation,Packaging,and Marking of Lime and Limestone ProductsC51 Terminology Relating to Lime and Limestone(as usedby the Industry)C110 Test Methods for Physical Testing of Quicklime,Hydrated Lime,and LimestoneC1271 Test Method for X-ray Spectrometric Analysis ofLime and LimestoneC1301 Test Method for Major and Trace Elements in Lime-stone and Lime by Inductively Coupled Plasma-AtomicEmission Spectroscopy(ICP)and Atomic Absorption(AA)D8 Terminology Relating to Materials for Roads and Pave-mentsD242 Specification for Mineral Filler For Bituminous Pav-ing MixturesD546 Test Method for Sieve Analysis of Mineral Filler forBituminous Paving Mixtures3.Terminology3.1 For definitions of terms used in this specification,referto Terminology C51 or Terminology D8.4.Chemical Requirements4.1 Hydrated lime for use in asphalt cement or bituminouspaving mixtures shall conform to the following chemicalcomposition:Calcium and Magnesium Oxides(on an LOI-free basis),min,%90.0Carbon Dioxide(taken at point ofmanufacture),max,%5.0Unhydrated Calcium and MagnesiumOxides,max,%5.0Free Moisture of Dry Hydrates(taken atpoint of manufacture),max,%2.04.2 The chemical analysis of the hydrated lime shall bedetermined in accordance with Test Methods C25,C1271,orC1301.5.Physical Requirements5.1 Hydrated lime,either dry or slurry form,shall not havemore than 3.0%retained on a 600 m(No.30)sieve and notmore than 30%retained on a 75 m(No.200)sieve.NOTE3Specification D242 also contains physical specifications forhydrated lime.Specification D242 includes four size gradations,expressedas percent passing the sieve.For the two size gradations included in bothSpecification D242 and Specification C1097,the specifications are thesame.5.2 The particle size of hydrated lime shall be determined inaccordance with Test Methods C110.NOTE4Some hydrated limes may require a full 30-min wash time.NOTE5The Test Methods C110 method for particle size analysis isrequired instead of the Test Method D546 method because the Test1This specification is under the jurisdiction of ASTM Committee C07 on Limeand is the direct responsibility of Subcommittee C07.02 on Specifications andGuidelines.Current edition approved Dec.1,2013.Published January 2014.Originallyapproved in 1990.Last previous edition approved in 2012 as C1097 07(2012).DOI:10.1520/C1097-13.2For 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 Methods C110 method uses a standardized spray nozzle and pressuregauge.6.Sampling,Inspection,Packaging and Marking6.1 Thesampling,inspection,rejection,retesting,packaging,and marking shall be done in accordance withPractice C50.7.Keywords7.1 additive;asphalt;bituminous;hydrated;lime;mineralfiller;mixtures;modifier;pavingASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.Users of this standard are expressly advised that determination of the validity of any such patent rights,and the riskof infringement of such rights,are entirely their own responsibility.This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised,either reapproved or withdrawn.Your comments are invited either for revision of this standard or for additional standardsand should be addressed to
