Abstract	In an effort to better understand the structure and behaviour of bitumen in low temperature, we describe the first user of cryogenic atomic force microscopy and phase detection microscopy to characterize bitumen nano- and microstructures. The results were interpreted in light of glass transition temperatures (Tgs) for bitumen fractions. The domains visible by microscopy, the catana, peri and para phases, were attributed to domains rich in asphaltenes, naphthene and polar aromatics, and saturates, respectively.
