1.1 This specification covers fine aggregate for use in asphalt paving mixtures. 1.2 This specification is intended to describe material from a single source. When material from two or more sources is to be blended to produce a grading to meet requirements in other specifications for asphalt paving mixtures, the grading requirements of Table 1 of this specification are not applicable. Note 1: When obtaining materials from two or more sources that are to be blended to produce the final mix, it is recommended that the specifying or the ordering agency specify the alternative gradings and blend ratios to be supplied. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Sieve numbers shown in the text and Table 1 are labels only and are included for ease of reference of the user of this standard. 1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
