Empirical Modeling of Viscosities and Softening Points of Straight-Run Vacuum Residues from Different Origins and of Hydrocracked Unconverted Vacuum Residues Obtained in Different Conversions

Energies, 2022
The use of hydrocracked and straight-run vacuum residues in the production of road pavement bitumen requires a good understanding of how the viscosity and softening point can be modeled and controlled.

Evaluating the storage stability of SBR-modified asphalt binder containing polyphosphoric acid (PPA)

Case Studies in Construction Materials, 2022
The poor storage stability of polymer-modified asphalt (PMA) binder hinders its applications. Traditionally, the softening point test is utilized to evaluate the storage stability, which shows less sensitivity compared with the rheological test.

The origin point of the unstable solution area of a forced softening Duffing oscillator

Scientific Reports, 2022
Each Duffing equation has an unstable solution area with a boundary, which is also a line of bifurcation. Generally, in a system that can be modeled by the Duffing equation, bifurcations can occur at frequencies lower than the origin point frequency of ...
