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
