Measurement and thermodynamic modeling of wax precipitation in asphalt …
Asphalt is in a flow state at high temperatures and will gradually change from a flow state to a solid state when cooled. From a thermodynamic point of view, the precipitation of wax is a transformation process of long-chain n-alkanes from liquid to solid phase. At a certain temperature, the asphalt must be in an equilibrium state consisting of ...
