1.1 本规范涵盖适用于沥青路面混合料的碎钢渣粗骨料和细骨料。 1.2 目前完全使用钢渣粗骨料和细骨料( 注1 )或与其他矿物骨料结合，如规范中涵盖的矿物骨料 D692/D692M 或 D1073号 ，以生产与规范中所述相似的铺路混合料 D3515 或 D4215 . 注1: 当100 % 沥青混合料中的粗骨料为钢渣，可限制该混合料中钢渣细粒的数量，以防止膨胀。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 注2: 筛孔尺寸由规范中的标准名称确定 E11 . 括号中给出的替代名称仅供参考，并不代表不同的标准筛孔尺寸。 1.4 本规范的正文引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers crushed steel slag coarse and fine aggregates suitable for use in asphalt paving mixtures. 1.2 Steel slag coarse and fine aggregates are currently being used entirely ( Note 1 ) or combined with other mineral aggregates, such as those covered in Specification D692/D692M or D1073 , to produce paving mixtures similar to those described in Specification D3515 or D4215 . Note 1: When 100 % of the coarse aggregate in an asphalt mixture is steel slag, the amount of steel slag fines in that mixture may be limited to prevent bulking. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Note 2: Sieve size is identified by its standard designation in Specification E11 . The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. 1.4 The text of this specification 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.
