| Abstract | Bitumen is a complex mixture of hydrocarbons for which the knowledge of microstructure is incomplete. In an effort to detail this microstructure, thirteen bitumens were analyzed by phase detection atomic force microscopy. Based on morphology, the bitumens could be classified into three distinct groups. One group showed fine domains down to 0.1 ìm, another showed domains of about 1 ìm, and a third group showed up tofour different domains or phases of different sizes and shapes. No correlation was found between the AFM morphology and the composition based on asphaltenes, polar aromatics, naphthene aromatics and saturates. A good correlation was found between the area of the 'bee-like' structures and the vanadium and nickel content in bitumen, and a good correspondence was found between the AFM groups and the average size of molecular planes made of fused aromatics. The morphology and the moleculararrangements in bitumen thus appear partly governed by the molecular planes and the polarity defined by metallic cations. |
