Abstract
Described herein are asphaltite-based adducts and polymers and methods of making the same. Asphaltite may be modified with a reagent such as polyphosphoric acid. The reagent may modify the asphaltite or portions or moieties thereof to possess a positive charge. The reagent may also activate the asphaltite or portions thereof to enable epoxy and/or urethane polymerization reactions within the asphaltite or portions thereof, and/or to enable cross-linking of the asphaltite-based polymers or adducts. Products incorporating asphaltite-based polymers and adducts are also described.

An asphalt composition, comprising:
- a blend of an asphalt binder, asphaltite, and a polymer;
- and
- an acid that is at least one of a strong acid or a multiprotic acid;
- wherein the acid causes polar resins in the asphaltite to be in an excited protonated state;
- wherein the polymer comprises an alkene, ester, carbonyl, or alcohol moiety or is a urethane or an epoxy;
- wherein the polymer is incorporated into the asphalt binder and the asphaltite such that the blend has a continuous, amorphous phase;
- and
- wherein the blend exhibits at least one change to a rheological property compared to the asphalt binder and the asphaltite alone.
A method of making an asphalt composition, comprising:
- blending an asphalt binder, asphaltite, and a polymer to form a blend;
- and
- adding an acid that is at least one of a strong acid or a multiprotic acid to the blend in an amount sufficient to cause polar resins in the asphaltite to be in an excited protonated state;
- wherein the polymer comprises an alkene, ester, carbonyl, or alcohol moiety or is a urethane or an epoxy;
- wherein the polymer is incorporated into the asphalt binder and the asphaltite such that the blend has a continuous, amorphous phase;

A cold mix recycled asphalt pavement, comprising:
- a mixture of an aggregate comprising recycled pavement and an asphalt emulsion;
- wherein the asphalt emulsion constitutes between about 2.5% to about 6% by total weight of the mixture;
- wherein the asphalt emulsion comprises:
- a blend of an asphalt binder, asphaltite, and a polymer, the blend in an amount of between about 50% to about 70% by weight of the emulsion;
- an acid that is at least one of a strong acid or a multiprotic acid;
- an emulsifying agent in an amount of between about 1.0% to about 3.5% of the emulsion;
- and
