Status of AASHTO Materials Standards and Test Methods—August 2017This document shows all materials specifications, practices, and test methods that have been published as part of the AASHTO StandardSpecifications for Transportation Materials and Methods of Sampling and Testing from its first publication in 1931 through the most recentedition.The chart on the following pages shows each AASHTO standard, in numerical order. Information includes the standard’s original and currenttitles, the year it was adopted, and its current status. Active AASHTO standards are shown with a white background; standards which are nolonger active are shown with a gray background. For standards that are no longer active, the chart also shows the date the standard wasdiscontinued, as well as the reason for its discontinuation, if known. If a substitute standard—either from AASHTO or another organization—hasbeen identified to be used instead, its number is also provided. Finally, the Notes column contains any additional relevant information about thepublication history of the standard.AASHTO StandardsAASHTO materials standards consist of a single letter indicating the standard type and a one- to three-digit number uniquely identifying thestandard. This is followed by second number indicating the date of most recent revision and, if applicable, review. These dates change frequentlyand are not shown in this list.Standard TypesStandard types are represented by a one-letter abbreviation for full standards. The letter “P” is added for provisional standards, which arelisted separately for Part 3. The abbreviations for full standard types are as follows: M (Materials)R (PRactice)T (Test)Standard NumbersStandard numbers are sequential within standard type.
