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.
