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.

Claim (Index 14):
Bitumen/polymer composition comprising:\n bitumen, at least one elastomer, and at least one olefinic polymer adjuvant functionalized by at least glycidyl functional groups, wherein: the elastomer is selected from thermally crosslinkable block copolymers of formula S-B1-B2, in which S represents a monovinylaromatic hydrocarbon block having a peak molecular weight of from 10 000 to 25 000, B1 is a polybutadiene block having a vinyl content of less than or equal to 15 mole percent, B2 is a polybutadiene block having a vinyl content of greater than or equal to 25 mole percent, the B 1/B2 weight ratio is greater than or equal to 1:1, and in which the S-B 1-B2 block copolymer has a peak molecular weight of from 40 000 to 200 000; the elastomer may also comprise at least one thermally crosslinkable block copolymer corresponding to the formula (S-B1-B2) n X in which each S represents a monovinylaromatic hydrocarbon block having a peak molecular weight of from 10 000 to 25 000, each B1 represents a polybutadiene block having a vinyl content of less than or equal to 15 mole percent, each B2 represents a polybutadiene block having a vinyl content of greater than or equal to 25 mole percent, n is an integer ranging from 2 to 6, and X is the residue of a coupling agent, in which the B1/B2 weight ratio is greater than or equal to 1:1, and the (S-B1-B2) n X block copolymer has a peak molecular weight which is from 1.5 to 6.0 times the peak molecular weight of the S-B1-B2 block copolymer; and the elastomer/adjuvant weight ratio in the composition ranges from 15/1 to 2/1.
