A subject of the present invention is a composition comprising: at least one recycled bituminous product, at least one epoxidized oil, and at least one bitumen additive.

The invention also relates to the use thereof for the preparation of a mix. Another subject of the invention is a mix comprising the composition according to the invention.

The present invention provides an asphalt composition containing an asphalt and a polyester, the polyester being a polycondensate of a polyethylene terephthalate, an alcohol, and a carboxylic acid compound, the polyethylene terephthalate having a value of [(a quantity of heat absorbed in a DSC measurement)−(a quantity of heat generated in a DSC measurement)] of 5 J/g or more and 30 J/g or less and having an intrinsic viscosity (IV) of 0.6 or more and 1.05 or less.

Provided is a cover for asphalt including an asphalt emulsion and a method of paving asphalt using the same, and specifically, to a cover for asphalt, which may facilitate adhesion between an existing asphalt pavement layer and a new asphalt pavement layer and substitute for a tack coat. The cover for asphalt prevents an asphalt emulsion from being damaged by heavy vehicles or construction equipment moving for application of a new pavement layer, and allows omitting separate asphalt emulsion application and curing processes before application of the new asphalt layer.

An oil-in-water emulsion comprising an asphalt and purified coal product (PCP) is provided, wherein the PCP is in particulate form, and wherein at least about 90% by volume (% v) of the particles are no greater than about 25 μm in diameter; wherein the PCP has an ash content of less than about 10 wt %. Methods are also provided for the use of PCP as a stabilizing additive in the manufacture of asphalt containing emulsions.

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.

Asphalt-based compositions for use in the restoration of low-sloped roofs. Compositions are a unique combination of PG asphalts, elastomers, plastomers, plasticizers, and waxes having the unique physical property of providing a functional membrane that can be applied over existing roofing membranes and materials.
