本文件规定了测定再生沥青中粗杂质含量和成分的目视方法。附录A中给出了测定再生沥青中较细杂质含量和成分的方法。该方法不能完全分类再生沥青中可能出现的杂质。 注:在沥青混合料中使用再生沥青时，必须了解再生沥青中的成分，以及粗杂质在多大程度上会影响沥青混合料的性能。

This document specifies a visual method of determining the amount and components of coarse foreign matter in reclaimed asphalt. A method for determining the amount and components of finer foreign matter in reclaimed asphalt is given in Annex A. This method does not completely categorize the foreign matter that can occur in reclaimed asphalt. NOTE For the use of reclaimed asphalt in bituminous mixtures it is important to know the components in the reclaimed asphalt and to know to what extent coarse foreign matter is present that can influence the properties of the bituminous mixture.
