Abstract
Thermally crosslinkable bitumen/polymer composition based on at least one elastomer of S-B1-B2 type, with S a styrene polymer or other vinylaromatic polymer, B1 and B2 polybutadienes, the composition including an adjuvant of olefinic polymer type, the composition having improved mechanical properties. Use of these compositions in the fields of road applications such as hot bituminous mixes; warm bituminous mixes; cold bituminous mixes, for example cold-poured bituminous mixes or emulsion gravels; or surface dressings, for example fluxed bitumens or emulsions; and in the fields of industrial applications, for example in the manufacture of internal and external coatings.
