FIELD: chemistry.
SUBSTANCE: invention relates to additives for use in bitumen and polymer-modified bitumen. The additive is obtained by mixing the following: (a) sulphur, (b) vulcanised rubber, e.g. vulcanised rubber wastes, (c) a fatty acid and (d) bitumen.
EFFECT: use of said additive to obtain, for very limited gas emissions, an elastomer-containing bitumen product which is particularly suitable for producing bitumen-coated material with improved processing properties, such as asphalt concrete.
