Ordering Information4.1 When ordering under this specification, include in thepurchase order the performance grade (PG) of asphalt binderrequired a
34、nd the table used (for example, PG 52-16, Table 1 orPG 64-34, Table 2). If no table is specified, the default is Table1.NOTE 3Agencies may elect to specify PG grades not listed in thetables, either outside the table limits or between listed grades, based onspecific design or performance criteria. Fo
35、r these PG grades it is stillappropriate to test the original and RTFO DSR at the specified PG hightemperature, and BBR at the specified PG low temperature +10 C andPAV DSR at (PG high + PG low)/2 + 4) C, for example, for PG 64-22,(64 + (-22)/2+4=25.5. Materials and Manufacture5.1 Asphalt binder sha
36、ll be prepared by the refining of crudepetroleum, from naturally occurring asphalt, or combinationsthereof, by suitable methods, with or without the addition ofmodifiers.5.2 Modifiers may be any materials of suitable manufacturethat are used in virgin or recycled condition, and that arecapable of be
37、ing dissolved, dispersed or reacted in asphaltbinder with the objective of improving its performance.NOTE 4This specification is not intended to address the grading ofasphalt binders containing particulate or fibrous materials larger than 250m in size.5.3 The asphalt binder shall be homogeneous, fre
38、e fromwater and deleterious materials, and shall not foam whenheated to 175C.5.4 The asphalt binder shall be at least 99.0 % soluble, asdetermined by Test Methods D2042, D7553,orD5546. Anyinsoluble component shall be substantially free of fibers.5.5 The grades of asphalt binder shall conform to ther
39、equirements given in Table 1 or Table 2NOTE 5Conformance with all of the parameters of this specification isnot a guarantee that the asphalt concrete mix made from these productswill perform in the field. The end user of asphalt binders should assess thesuitability of the binder to meet the performa
40、nce requirements of theprojects on which they will be used.6. Sampling6.1 The material shall be sampled in accordance withPractice D140.7. Test Methods7.1 The properties outlined in 5.3, 5.4 and 5.5 shall bedetermined in accordance with Test Methods D92, D95,D2042, D2872, D4402, D5546, Practice D652
41、1, Test MethodsD6648 and D6723, Practice D6816, and Test Methods D7553or D7175.8. Inspection and Certification8.1 Inspection and certification of the material shall beagreed upon between the purchaser and the seller. Specificrequirements shall be made part of the purchase contract. Theseller shall p
42、rovide material handling and storage proceduresfor each asphalt binder grade certified.NOTE 6A number of relevant research studies have suggested thatlimits for the loss stiffness for the binder, G*sin, in the ASTM andAASHTO PG Binder Specification is, by itself, not a sufficient indicatorof fatigue
43、 performance of an asphalt cement, or the asphalt concrete inasphalt pavement structures, or both.9. Rejection and Rehearing9.1 If the results of any test do not conform to the require-ments of this specification, retesting to determine conformity isperformed as indicated in the purchase order or as
44、 otherwiseagreed upon between the purchaser and the seller.10.

SUMMARY OF DIFFERENCES BETWEEN SPECIFICATION D6373 AND AASHTO M 3
45、2010X1.1 This specification was originally developed under thesponsorship of theAmericanAssociation of State Highway andTransportation Officials (AASHTO) as part of the StrategicHighway Research Program (SHRP). ASTMs version of thisspecification (Specification D6373) was modeled after, and issimilar
46、 to the comparable AASHTO specification (AASHTOM-320, formerly known as PP 1).X1.1.1 The 2013 and 2015 revisions of the ASTM specifi-cation include several changes that bring the ASTM andAASHTO standards into closer alignment. To help the userunderstand the relationship between these standards, and
47、in theinterest of promoting further harmonization, the remainingdifferences are summarized below. Note that ASTM andAASHTO may use slightly different formats and sectionD6373 164numbering, so this summary is intended for general informa-tion only. Please consult the corresponding ASTM andAASHTO stan
48、dards to determine the exact differences.X1.2 Differences in the Scope Section (Section 1 in bothstandards)X1.2.1 The ASTM standard references ASTM test methodwhile the AASHTO standard references AASHTO test meth-ods.X1.3 Differences in the Referenced Documents Section(Section 2 in both standards)X1.3.1 In most cases, theASTM Standard referencesASTMdocuments, while the AASHTO Standard references AASHTOdocuments. The correspondence between the referenced docu-ments is given in the following table. These differences occurin the referenced document section (Section 2), as
