Abstract: Dispersed structures in bitumen BND 40/60, kept at a room temperature for 3 years have been studied by the methods of scanning calorimetry (DSC). DSC of group chemical components of bitumen and reheating of each sample (to detect anomalies in the vanishing of DSC curves) has been used to identify these structures. We identify the following structures (and their temperature destruction): crystals of saturated compounds, paraffin and asphaltenic complexes, micelles and their coagulation structure, asphaltenic nanoaggregates.

Keywords: oil bitumen, dispersion patterns, differential scanning calorimetry.
