Abstract

A composition that includes asphalt component; and graphite component.

First claim

The invention claimed is:

1. A composition comprising:
asphalt component; and
about 3 wt % to about 6 wt % of graphite nanoplatelets with respect to the weight of the asphalt component.

2. The composition according to claim 1 , wherein the asphalt component comprises asphalt binder.

3. The composition according to claim 1 , wherein the asphalt component comprises roof binder, asphalt emulsion, recycled asphalt pavement (RAP), recycled asphalt shingles (RAS), or a combination thereof.

4. The composition according to claim 1 further comprising aggregate.

5. The composition according to claim 1 , wherein the asphalt component comprises asphalt binder and recycled asphalt pavement (RAP).

6. The composition according to claim 1 , wherein the asphalt component comprises asphalt binder and recycled asphalt shingles (RAS).

7. A method of forming a composition comprising: mixing asphalt binder and about 3 wt % to about 6 wt % of graphite nanoplatelets to form a binder composition.

8. The method according to claim 7 wherein the graphite component is added to the asphalt binder.

9. The method according to claim 7 further comprising adding the binder composition to aggregate to form a paving composition.

10. The method according to claim 9 further comprising depositing the paving composition in a desired area and compacting the deposited paving composition to form pavement.

11. The method according to claim 10 , wherein the paving composition is deposited in an area of existing pavement.

12. The method according to claim 7 further comprising adding the binder composition to recycled asphalt pavement (“RAP”) to form a paving composition.

13. The method according to claim 7 further comprising adding the binder composition to reclaimed asphalt shingles (“RAS”) to form a shingle forming composition.

14. The method according to claim 13 further comprising forming a shingle from the shingle forming composition.

15. A composition comprising:
asphalt component comprising asphalt binder selected from the group consisting of PG 58-28, PG 52-34, PG 64-34, and combinations thereof; and
about 3 wt % to about 6 wt % of graphite component comprising graphite nano-platelets, graphite micro-flakes, or a combination thereof.

16. The composition according to claim 15 , wherein the graphite component comprises, graphite micro-flakes.

17. The composition according to claim 15 , further comprising recycled asphalt pavement (RAP).
