Dividing a material into its constituent parts is necessary to define its composition. Researchers can use these compositional analyses for binder formulation through blending, rejuvenation, and modification, as well as for predicting physical performance. The most common type of analysis divides a crude oil or asphalt into saturate, aromatic, resin, and asphaltene fractions. This technical brief focuses on the use of an automated high-performance liquid chromatography process that also further separates the asphaltene fraction.
