  • Additive for a bitumen and bituminous product
    Patent number: 9029439
    Abstract: An additive for a bitumen or polymer modified bitumen product, which is prepared by mixing together a sulphur-based product, a vulcanized rubber, for example, a waste vulcanized rubber, preferably a fatty acid, and a bitumen, is described. The use of this additive for preparing, with very limited gaseous emissions, elastomer-containing bituminous product is also described. Such use may be especially suitable for making bituminous coated material including, for example, asphalt concrete.
