| abstract |
The invention relates to a bituminous composition and to the method for the production thereof. The bituminous composition comprises a bitumen, a first additive comprising at least one linear or branched, saturated or unsaturated fatty acid ester function, having a hydrocarbonated chain of between 4 and 36 carbon atoms, optionally substituted by at least one hydroxyl group, and a second additive comprising at least one organogelling compound. The invention also relates to the use of a combination of the first and second additives in a bituminous composition, for reducing the dynamic viscosity of a bituminous composition or a bitumen base to a temperature higher than or equal to 80°C, preferably higher than 80°C, without degrading the consistency of said composition at temperatures of use. The invention further relates to the use of said bituminous compositions in the fields of road applications, especially in the production of road binders, and in the fields of industrial applications. |
