ABSTRACT:
A tag is added to an asphalt additive, typically an anti-stripping agent. The additive dye is mixed with other components of an asphalt composition and melt processed at 300.degree. F. (149.degree. C.) or above to produce an asphalt composition. Presence of the tag to identify presence of the additive is performed by dissolving the asphalt portion of the composition in a water-immiscible solvent and then extracting the tag in an acidic aqueous solution and developing a color with a diazo compound.
