Asphaltene precipitation under controlled mixing conditions in a microchamber [PDF]
Chemical engineering journal, 2022, 2022 Solvent exchange is a controlled process for dilution-induced phase separation. This work utilizes the solvent exchange method to reveal the effect of the mixing dynamics on the asphaltene precipitation process under 20 different mixing conditions using a model system of n-heptane and asphaltene in toluene.

High-Temperature Performance Evaluation of Asphaltenes-Modified Asphalt Binders
Molecules, 2020 Asphalt binder comprises four main fractions—asphaltenes (A), saturates (S), aromatics (A), and resins (R)—referred to as “SARA”. Asphaltenes plays an important role in determining the linear viscoelastic behavior of asphalt binders.
