TLDR
In this article, a new understanding about bitumen's colloidal behavior, related to its chemical composition, microscopic structure and rheological properties, is given, which is based on the ratio of the four main chemical components (asphaltenes, resins, aromatics, saturates).About:

A review of the fundamentals of polymer-modified asphalts: Asphalt/polymer interactions and principles of compatibility
TL;DR: The chemical, physical, and processing solutions suggested in the scientific and patent literature to improve storage stability are extensively discussed, with particular attention to an emerging class of asphalt binders in which the technologies of polymer-modified asphalts and polymer nanocomposites are combined.
Journal ArticleDOI
Bitumen morphologies by phase-detection atomic force microscopy.
TL;DR: The morphology and the molecular arrangements in bitumen thus appear to be partly governed by the molecular planes and the polarity defined by metallic cations.

Interfacial sciences in unconventional petroleum production: from fundamentals to applications
TL;DR: In this critical review, the recent research findings and progress in the interfacial sciences related to unconventional petroleum production are critically reviewed and the chemistry of unconventional oils, liberation mechanisms of oil from host rocks and mechanisms of emulsion stability and destabilization in unconventional oil production systems are discussed in detail.

Morphology of asphalts, asphalt fractions and model wax-doped asphalts studied by atomic force microscopy
TL;DR: In this paper, the interaction between crystallising paraffin waxes and the remaining asphalt fractions is hypothesized to be responsible for much of the structuring, including the well-known bee structures.
Journal ArticleDOI
Improving the aging resistance of styrene-butadiene-styrene tri-block copolymer modified asphalt by addition of antioxidants
TL;DR: In this paper, the aging properties of base asphalt and styrene-butadiene-styrene tri-block copolymer (SBS) modified asphalts (PMA) were evaluated using Fourier Transform Infrared (FTIR) spectroscopy.

Macrostructure of asphaltene dispersions by small-angle X-ray scattering
P. Herzog,D. Tchoubar,D. Espinat +2 more
TL;DR: In this article, three asphaltene dispersions have been studied by small-angle X-ray scattering, and the macrostructure model used for the curve simulations is based upon a distribution of thin discs which all have the same thickness (3.4 A) and a radius which follows a power law such as r β (13 A ⩽ r ⌽ 800 A ), which suggests that these membranes could result from the aggregation of small Yen's elementary units.
