SUMMARY OF DIFFERENCES BETWEEN SPECIFICATION D 6373 AND AASHTO M 32005X1.1 This specification was originally developed under thesponsorship of theAme

41、ricanAssociation of State Highway andTransportation Officials (AASHTO) as part of the StrategicHighway Research Program (SHRP). ASTMs version of thisspecification (Specification D 6373) was modeled after, and issimilar to the comparable AASHTO specification (AASHTOM-320, formerly known as PP 1).X1.1

42、.1 The 2007 revision of the ASTM specification in-cludes several changes that bring the ASTM and AASHTOstandards into closer alignment. To help the user understand therelationship between these standards, and in the interest ofpromoting further harmonization, the remaining differences aresummarized

43、below. Note that ASTM and AASHTO may useslightly different formats and section numbering, so thissummary is intended for general information only. Pleaseconsult the corresponding ASTM and AASHTO standards todetermine the exact differences.X1.2 Differences in the Scope Section (Section 1 in bothstand

44、ards)X1.2.1 There are minor editorial differences in the firstsentence.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.
