FIELD: construction. ^ SUBSTANCE: invention is related to production of construction materials by means of oil refinery wastes processing. Invention is related to method for production of bitumen from acid tar, including its heating, neutralisation and oxidation, realised with electrochemical method, at the stage of oxidation a modifying additive is additionally introduced - magnetised oil product in amount of 1-10 wt %, comprising the following components: magnetite Fe3O4, kerosene and oleic acid. ^ EFFECT: due to electric conductivity of acid tar and with application of modifying additive, it becomes possible to produce oxidised bitumen within 60 minutes with parametrers that correspond to oil construction bitumen BN 70/30 (GOST 6617-76*). ^ 6 ex, 2 tbl |
