Изобретение относится к способу получения дорожных битумов из нефтяных остатков и может быть использовано в нефтепераработке. Способ заключается в деасфальтизации нефтяных остатков с последующим смешиванием асфальта деасфальтизации с нефтяным разбавителем, например, экстрактом селективной очистки, гудроном. Для повышения технологичности способа, уменьшения количества используемого разбавителя, увеличения выхода битумов деасфальтизацию проводят пропан-бутановым растворителем, а в качестве разбавителя используют дополнительно к вышеуказанным полугудрон, мазут, затемненную фракцию, крекинг-остаток или аналогичные по вязкости нефтепродукты. При этом оптимальное содержание пропана в пропан-бутановом растворителе составляет 9 - 45.The invention relates to a method for producing road bitumen from oil residues and can be used in oil refining. The method consists in the deasphalting of oil residues with the subsequent mixing of asphalt deasphalting with oil diluent, for example, the extract of selective cleaning, tar. To improve the processability of the method, reduce the amount of diluent used, increase the bitumen yield, deasphalting is carried out with a propane-butane solvent, and in addition to the above, semi-impurities, fuel oil, darkened fraction, cracking residue or similar viscosity oil products are used. The optimal content of propane in propane-butane solvent is 9 - 45.
