Separation of Asphalt Into Four Fractions, Standard Test Methods For
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 These test methods cover the separation of four defined fractions from petroleum asphalts. The four fractions are defined as saturates, naphthene aromatics, polar aromatics, and nC7-asphaltenes. These methods can also be used to isolate saturates, naphthene aromatics, and polar aromatics from distillate products such as vacuum gas oils, lubricating oils, and cycle stocks. These distillate products usually do not contain asphaltenes.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 his 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. Specific precautionary statements are given in Section 8 and 15.
Significance and Use
This test method separates asphalts into four well-defined fractions. Analysis of these fractions can be used to evaluate asphalt composition. For example, one can compare the ratios of the fractions with other asphalt systems to evaluate processing and aging parameters that relate to performance properties of the asphalt.
