Abstract:
1. Anhydrous bituminous products, characterized in that they contain at least one additive selected from the group consisting of: A: random or block ethylene oxide/propylene oxide copolymer(s) having a molecular weight between 500 μg/mol and 20 000 g/mol, with a weight ratio of ethylene oxide to (ethylene oxide+propylene oxide) between 1% and 70%, of which the overall dose per metric ton of bituminous product is between 0.1 and 5 kg; B: blend of at least one A and at least one product A1 of chemical formula: (R—O—(CH C: blend of at least one product A or at least one product A1 or at least one product B and at least one product A2, in a dose of product(s) A per metric ton of bituminous product between 0.05 and 9 kg, in a dose of product(s) A1 or B per metric ton of bituminous product between 0.05 and 10 kg, in a dose of product(s) A2 per metric ton of bituminous product between 0.05 and 10 kg, A2 selected from the group consisting of: A21 the product of the reaction of (di)alk(en)ylphenols with aldehydes, the aldehydes having from 1 to 10 carbon atoms, followed by a (poly)oxyethylation and/or (poly)oxypropylation, the alk(en)yl groups having between 1 and 50 carbon atoms and possibly being identical or different in the case of dialk(en)ylphenols, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molecular weight greater than or equal to 45 g/mol and less than 20 000 g/mol, the number of phenol units varying between 3 and 50; A22 the (poly)oxyethylated and/or (poly)oxypropylated 2,2-bis(4-hydroxyphenyl)propane/epichlorohydrin copolymer, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molecular weight greater than or equal to 45 g/mol and less than 20 000 g/mol; A23 the (poly)oxyethylated and/or (poly)oxypropylated bis(4-hydroxyphenyl)ethane/epichlorohydrin copolymer, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molecular weight greater than or equal to 45 g/mol and less than 20 000 g/mol; A24 the (poly)oxyethylated and/or (poly)oxypropylated bis(4-hydroxyphenyl)methane/epichlorohydrin copolymer, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molecular weight greater than or equal to 45 g/mol and less than 20 000 g/mol; A25 the product of the (poly)oxyethylation and/or (poly)oxypropylation of an alkyldicarboxylic acid or mixture of alkyldicarboxylic acids, the alkyl groups having between 1 and 20 carbon atoms, all of the parts formed by (poly)oxyethylation and/or (poly)oxypropylation having a molecular weight greater than 100 g/mol and less than 20 000 g/mol; A26 the product of the (poly)oxyethylation and/or (poly)oxypropylation of a fatty acid, the number of carbon atoms of which is between 10 and 30, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molecular weight greater than 100 g/mol and less than 20 000 g/mol; A27 the product of the reaction between the product A21 and a mixture of A25 and A26; A28 the salt of alk(en)yl(aryl)sulfonic acid and alk(en)yl(aryl)amine, the alk(en)yl(aryl) units having a number of carbon atoms between 6 and 30; and/or A29 the salt of alk(en)yl(aryl)sulfonic acid and morpholine or pyrazine or pyrazoline or pyrazolone or pyridine or pyridone or pyrimidine or pyrrole or pyrrolidine or pyrrolidone or pyrroline or toluidine or imidazole or indole or indoline or oxindole, the alk(en)yl(aryl) units having a number of carbon atoms between 6 and 30; and D: blend of at least one product A or at least one product B or at least one product C and one or more adhesion dopes, the dose of product(s) B or C per metric ton of bituminous product being between 0.1 and 10 kg, the dose of product(s) A per metric ton of bituminous product being between 0.05 and 9 kg, the dose of adhesion dope(s) per metric ton of bituminous product being between 0.05 and 10 kg, the weight ratio of the product A, B or C to the adhesion dope(s) being between 90/10 and 10/90.
