Roofing bitumens have a higher softening temperature (85 - 95 C) and a smaller depth of needle penetration, while for insulating bitumens the extensibility index is important. It is usually prepared from residual bitumen of low density. Roofing bitumen contains a certain amount of cycloparaffin and paraffin hydrocarbons and approximately 30% asphaltenes. The ratio of carbon and hydrogen in it is also increased; as a result, the dissolving capacity of such bitumens decreases and the mutual attraction of asphaltenes increases.
Asphaltenes also attract heavy aromatic components, but the probability of other components joining with these aggregates is very low. Such a system can be considered at high temperatures as a concentrated solution of a solid substance in an oil medium. When cooled, the asphaltenes precipitate and form complexes that resemble crystallites. This process is so rapid that the aggregates are extremely small; this corresponds to the general law that the ratio of the surface of a crystal to its volume is greatest at high growth rates.
An equally important factor determining the quality of bitumen is the method of its production. The production of roofing bitumen in the practice of oil refining both in Ukraine and abroad is carried out mainly by oxidation of the corresponding oil residual products. In Ukraine, the main amount of oxidized bitumen is produced in batch cubes.
For most bitumens, the ability to water saturation is revealed already during the first day. Therefore, the technical requirements of GOST 9812 - 61 for petroleum roofing bitumens are limited to standardization of daily water saturation of bitumen. Studies of bitumens show that their physical and chemical properties are related to the fractional composition.
Knowledge of the optimal ratios of individual components of raw materials, as well as colloidal changes occurring during the production of bitumen, makes it possible to take a more qualified approach to the selection of raw materials and the method of processing them to obtain high-quality bitumen.However, the quality requirements for oils for the production of insulating bitumens differ significantly from the requirements for them for obtaining road bitumens. This is due to the specifics of their application, as well as the difference in the structural and colloidal state of viscous and solid bitumens.
