Abstract

A method comprises obtaining a virgin asphalt and obtaining an asphalt shingle waste. The asphalt shingle waste comprises 5 wt. % to 40 wt. % of asphalt based on the total weight of the asphalt shingle waste. The asphalt shingle waste comprises 60 wt. % to 95 wt. % of limestone, granules, and/or impurities based on the total weight of the asphalt shingle waste. The method comprises obtaining a phase modifier. The method comprises mixing the virgin asphalt, the asphalt shingle waste, and the phase modifier to form an asphalt mixture. The phase modifier is present in an amount of 0.25 wt. % to 25 wt. % based on the total weight of the asphalt mixture. The asphalt mixture is configured to be applied to a roof substrate to obtain a roofing shingle.

Claims (50)

1. A roofing shingle comprising:

a substrate,

wherein the substrate comprises a fiberglass mat; and

an asphalt shingle waste filled coating on the substrate,

wherein the asphalt shingle waste filled coating comprises:

an asphalt,

wherein the asphalt comprises:

 50% to 99% by weight of a virgin asphalt based on a total weight of the asphalt;

 1% to 50% by weight of a waste asphalt based on the total weight of the asphalt;

20% to 70% by weight of at least one filler based on a total weight of the asphalt shingle waste filled coating,

wherein the at least one filler comprises limestone; and

0.1% to 10% by weight of a phase modifier based on the total weight of the asphalt shingle waste filled coating;

wherein the phase modifier comprises at least one of a pine chemical additive, a renewable oil, or any combination thereof.

2. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 60% to 99% by weight of the virgin asphalt based on the total weight of the asphalt.

3. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 65% to 99% by weight of the virgin asphalt based on the total weight of the asphalt.

4. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 70% to 99% by weight of the virgin asphalt based on the total weight of the asphalt.

5. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 75% to 99% by weight of the virgin asphalt based on the total weight of the asphalt.

6. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 80% to 99% by weight of the virgin asphalt based on the total weight of the asphalt.

7. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 45% by weight of the waste asphalt based on the total weight of the asphalt.

8. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 40% by weight of the waste asphalt based on the total weight of the asphalt.

9. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 35% by weight of the waste asphalt based on the total weight of the asphalt.

10. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 30% by weight of the waste asphalt based on the total weight of the asphalt.

11. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 25% by weight of the waste asphalt based on the total weight of the asphalt.

12. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 20% by weight of the waste asphalt based on the total weight of the asphalt.

13. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 0.1% to 5% by weight of the phase modifier based on the total weight of the asphalt shingle waste filled coating.

14. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 0.1% to 3% by weight of the phase modifier based on the total weight of the asphalt shingle waste filled coating.

15. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 0.1% to 2% by weight of the phase modifier based on the total weight of the asphalt shingle waste filled coating.

16. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 0.1% to 1% by weight of the phase modifier based on the total weight of the asphalt shingle waste filled coating.

17. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 1% to 3% by weight of the phase modifier based on the total weight of the asphalt shingle waste filled coating.

18. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 0.25% to 2% by weight of the phase modifier based on the total weight of the asphalt shingle waste filled coating.

19. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 20% to 70% by weight of the asphalt based on the total weight of the asphalt shingle waste filled coating.

20. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 30% to 50% by weight of the asphalt based on the total weight of the asphalt shingle waste filled coating.

21. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 30% to 45% by weight of the asphalt based on the total weight of the asphalt shingle waste filled coating.

22. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 30% to 40% by weight of the asphalt based on the total weight of the asphalt shingle waste filled coating.

23. The roofing shingle of claim 1 , wherein the asphalt shingle waste filled coating comprises 50% to 70% by weight of the at least one filler based on the total weight of the asphalt shingle waste filled coating.
