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 by electrochemical method, at the stage of oxidation additionally modifying additive-oil-containing waste is introduced in amount of 5-30 wt %, which contains the following components: paraffin, crude oil.
EFFECT: due to electric conductivity of acid tar and with application of modifying additive, it takes 60 minutes to produce oxidised bitumen with parametres that correspond to construction oil bitumen BN 70/30 (GOST 6617-76*).
