Standard Practice for Infrared (IR) Procedure for Determination of Aromatic/ Aliphatic Ratio of Bituminous Emulsions

Significance and Use

5.1 The results of this practice may be used to distinguish tar-based emulsion from an asphalt-based emulsion for specification compliance purposes.


1.1 This practice uses infrared analytical techniques to qualitatively determine in the laboratory a ratio of aromatic absorbance to aliphatic absorbance. This practice may be used to determine if the bitumen in the emulsion is predominantly aromatic or aliphatic in nature.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
