The present invention relates to a road paving method enabling one to provide an asphalt paving material layer in which both excellent stability and stress relaxation can be made compatible with each other, the method including Step 1: a step of mixing asphalt, a thermoplastic elastomer, a polyester, and an aggregate to obtain an asphalt mixture, and Step 2: a step of laying the asphalt mixture obtained in Step 1 on a road, thereby forming an asphalt paving material layer, wherein the polyester has a softening point of 90° C. or higher and 140° C. or lower and a glass transition point of 40° C. or higher and 80° C. or lower, and a ratio of the polyester is more than 17 parts by mass and 50 parts by mass or less based on 100 parts by mass of the asphalt.

The present invention relates to a process for the preparation of an asphalt mix composition, said process comprising: (1) providing an asphalt composition and heating said composition to a temperature in the range of from 110 to 200° C.; (2) providing a granular material and heating said material to a temperature in the range of from 110 to 240° C.; (3) providing one or more thermosetting reactive compounds; (4) adding the one or more thermosetting reactive compounds provided in (3) to the asphalt composition obtained in (1) and homogenizing the mixture for a duration in the range of from 2 to 180 s; (5) adding the mixture obtained in (4) to the granular material obtained in (2) and homogenizing the slurry for a duration in the range of from 5 to 180 s. Further, the present invention relates to an asphalt mix composition obtained or obtainable by said process and its use.

The present invention relates to an asphalt product. The asphalt product includes an asphalt binder and a bio-oil blend comprising a mixture of a non-hydrogenated bio-oil and a partially hydrogenated bio-oil, where the bio-oil blend is mixed with the asphalt binder to form an asphalt product having a shear stiffness of 0.20 kPa to 11,000 kPa at a temperature ranging from 25° C. to 85° C. and/or a viscosity of 0.15 Pa.Math.s to 1.50 Pa.Math.s at a temperature ranging from 120° C. to 165° C. The present invention further relates to methods of producing an asphalt product and methods of applying an asphalt product to a surface.

Disclosed are asphalt binder compositions that contain at least one sterol or stanol additive, or blends of sterols and stanol additives, wherein the sterol or stanol additive is derived from an animal waste or manure source such as swine manure. These sterol and stanol-based additives improve various rheological properties of the asphalt binder compositions showing reduced and/or mitigated aging characteristics.

Pavement aging can be reduced by applying to an asphalt-containing pavement a topcoat layer or a surface treatment containing asphalt binder emulsion with sterols.

A bituminous mastic includes:—from 0.5% to 25% by mass of at least one hydrocarbon oil, the total content of paraffinic compounds of which, measured according to the ASTM d2140 method, is greater than or equal to 50% by mass, and preferably greater than or equal to 60% by mass, relative to the total mass of the oil,—from 15% to 60% by mass of bitumen,—from 20% to 60% by mass of fillers, and—at most 14%, by mass of at least one polymer, preferably chosen from elastomers, relative to the total mass of bituminous mastic. A method for preparing such a bituminous mastic and to the uses thereof, in particular in certain road and/or industrial applications.
