ABOUT AASHTO DESIGNATION NUMBERSAnatomy of a Designation NumberComponentsT xxx - 16Standard TypeTwo-Digit Revision YearStandard NumberM xxx-12 (2016)Four-Digit Reconfirmation YearStandard TypesStandard types are represented by a one-letter abbreviation for full standards. The letter “P” is added for provisionalstandards. The standard type abbreviations are as follows: M (Materials, full)T (Test, full)R (PRactice, full) MP (Materials, provisional)TP (Test, provisional)PP (Practice, provisional)Standard NumbersStandard numbers are sequential within standard type. Thus, a provisional that is subsequently adopted as a fullstandard will receive a new number.Revised vs. Reconfirmed and Discontinued vs. DeletedA full or provisional standard is designated as revised if technical changes have been balloted and approved byAASHTO’s Highways Subcommittee on Materials. A standard is designated as reconfirmed if it has undergonetechnical review to determine that it is up to date and in use and that it does not require revision; such a review isrequired: every four years for a full standard, andevery one or two years for a provisional standard, depending on its progress through its 8-year provisionallife cycle.If a standard is no longer used, it may be discontinued by Subcommittee vote, in which case the standard headerwill be published that year with a notice saying that the standard has been discontinued and giving a briefexplanation as to why. In subsequent years, the standard will be deleted from the book, meaning that it is no longermaintained.
