FIELD: construction materials industry; methods of reprocessing of the acidic goudron.
SUBSTANCE: the invention is pertaining to the field of construction materials industry, in particular, to the method of reprocessing of the acidic goudron. The method provides, that the acidic goudron is neutralized by alkali. The products of the neutralization are subjected to the thermal oxidation at presence of the modified additive in amount of 5-10 % per 100 % of the oxidable raw. The technical result of the invention is simplification of the production process.
EFFECT: the invention ensures simplification of the production process.
