The use of bitumen as a construction material dates back to antiquity. The materials in use
then were mostly naturally occurring in contrast to modern bitumens which have become …

This synthesis explores the state-of-the-knowledge and state-of-the-practice regarding the
latest updates on polymer-modified bitumens (PmBs). The information in this study was …

The Yen–Mullins model, also known as the modified Yen model, specifies the predominant
molecular and colloidal structure of asphaltenes in crude oils and laboratory solvents and …

New chemical compositions of model asphalts to represent the AAA-1, AAK-1 and AAM-1
asphalts of the Strategic Highway Research Program are proposed to enable molecular …

Emulsions of oil droplets in water but more typically water droplets in oil are common in the
production, transportation, and refining of petroleum and related products. Emulsions of …

With the ever increasing demand for energy to meet the needs of growth in population and
improvement in the living standards in particular in develo** countries, the abundant …

Asphaltene structure is one of the most controversial topics in petroleum chemistry. The
controversy is centered on the organization of aromatic cores within asphaltene molecules …

We report classical atomistic molecular dynamics simulations of four structurally diverse
model asphaltenes, a model resin, and their respective mixtures in toluene or heptane under …

Advances in high-resolution Fourier transform ion cyclotron resonance mass spectrometry
(FT-ICR MS) enable molecular-level characterization of ultracomplex asphaltene samples …

Asphaltenes, complex aromatic compounds from various carbonaceous sources, could be
obtained by solvent dissolution, filtration and adsorption. It was difficult to clarify the …
