40、 thesponsorship of theAmericanAssociation 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, for

To help the user understand therelationship between these standards, and in the interest ofpromoting further harmonization, the remaining d
42、ifferences aresummarized below. Note that ASTM and AASHTO may useslightly different formats and section numbering, so thissummary is intended for general information only.
