A method of forming an asphalt mixture can include mixing a bio-source material and a bitumen source to form a bitumen mixture. The bitumen mixture can be mixed with a catalyst to form the asphalt mixture. Particles can be added to the asphalt mixture to form a roofing-grade asphalt mixture. In an embodiment, the bitumen source material can have a softening point of at least approximately 93° C. and a penetration distance no greater than approximately 25 dmm. In another embodiment, the roofing-grade asphalt mixture can have a softening point of at least approximately 104° C., a penetration distance no greater than approximately 12 dmm, a viscosity of at least approximately 3000 cps at a temperature of 204° C., or any combination thereof. The asphalt mixture can be applied to a base material to form a roofing product. The asphalt mixture can be applied as a pavement product.

The present invention relates to an asphalt composition comprising asphalt or an asphalt mixture and to a silicon carbide-containing binder that can be heated by means of microwaves. The silicon carbide is present in the binder in particle form, the equivalent diameter of silicon carbide particles contained in the binder is less than 60 μm. The invention also relates to a method for producing and/or renovating road surfaces or asphalt surfaces comprising at least one asphalt surface layer.

Bituminous compositions include molecules of formula (I). The use of these bituminous compositions is in the fields of road applications, particularly in the production of road binders and roadways in general, as well as in the fields of industrial applications. There is a method for preparing these bituminous compositions, and novel molecules of formula (I) can be used in particular in the formulation of bituminous compositions.
