FIELD: petroleum processing.
SUBSTANCE: modified acid sludge-based bitumen binder is prepared by heating, neutralizing, and oxidizing acid sludge performed by electrochemical way while further adding modifying additive in amount 5-20% and 10% of elementary sulfur, said additive being product of thermal destruction of rubber-cord waste obtained by autoclave technique.
EFFECT: improved performance characteristics of binder.
