Abstract

The present disclosure relates to asphalt paving compositions and methods of making and using the same.

Claims (31)

1 . An asphalt paving composition comprising:

an asphalt;

a natural asphalt;

one or more emulsifying agents;

one or more rejuvenating agents; and

one or more polymers.

2 . The asphalt paving composition of claim 1 , further comprising water.

3 . The asphalt paving composition of claim 1 , wherein the natural asphalt is an asphaltite.

4 . The asphalt paving composition of claim 1 , wherein the natural asphalt is Gilsonite.

5 . The asphalt paving composition of claim 1 , wherein the one or more emulsifying agents comprise 0.1-7.0% by weight of the total weight of the composition.

6 . The asphalt paving composition of claim 5 , wherein the one or more emulsifying agents comprise 0.35-1% by weight of the total weight of the composition.

7 . The asphalt paving composition of claim 5 , wherein the one or more emulsifying agents comprise 0.5-1.8% by weight of the total weight of the composition.

8 . The asphalt paving composition of claim 5 , wherein the one or more emulsifying agents comprise 1.5-3% by weight of the total weight of the composition.

9 . The asphalt paving composition of claim 1 , wherein the one or more rejuvenating agents comprise 1-95% by weight of the total weight of the composition.

10 . The asphalt paving composition of claim 9 , wherein the one or more rejuvenating agents comprise 6-12% by weight of the total weight of the composition.

11 . The asphalt paving composition of claim 9 , wherein the one or more rejuvenating agents comprise 2-4% by weight of the total weight of the composition.

12 . The asphalt paving composition of claim 9 , wherein the one or more rejuvenating agents comprise 1-6% by weight of the total weight of the composition.

13 . The asphalt paving composition of claim 1 , wherein the rejuvenating agent is Reclamite B.

14 . The asphalt paving composition of claim 1 , wherein the one or more polymers comprise 0.05-6.0% by weight of the total weight of the composition.

15 . The asphalt paving composition of claim 14 , wherein the one or more polymers comprise 2.0-4.0% by weight of the total weight of the composition.

16 . The asphalt paving composition of claim 14 , wherein the one or more polymers comprise 2.0-2.5% by weight of the total weight of the composition.

17 . The asphalt paving composition of claim 14 , wherein the one or more polymers comprise 0.1-1.0% by weight of the total weight of the composition.

18 . The asphalt paving composition of claim 1 , wherein one of the one or more polymers is a polychloroprene polymer.

19 . The asphalt paving composition of claim 18 , wherein the polychloroprene polymer is PA-AS-1 polychloroprene polymer.

20 . The asphalt paving composition of claim 1 , wherein one of the one or more polymers is a styrene butadiene rubber polymer.

21 . The asphalt paving composition of claim 1 , wherein the natural asphalt is Gilsonite, the rejuvenating agent is Reclamite B, and one of the one or more polymers is a PA-AS-1 polychloroprene polymer.

22 . The asphalt paving composition of claim 1 , wherein the asphalt and the natural asphalt are combined to form a modified asphalt.

23 . The asphalt paving composition of claim 22 , wherein the modified asphalt comprises 45-70% by weight of the total weight of the composition.

24 . The asphalt paving composition of claim 22 , wherein the modified asphalt is selected from: 80% w/w Valero BAP & 20% w/w Gilsonite; 83% w/w ASI Europe & 17% w/w Gilsonite; 82% w/w ASI Salt Lake blend Foreland AC & 18% w/w Gilsonite; 85% w/w “Nynas” ASI Europe & 15% w/w Gilsonite; 80% w/w San Joaquin & 20% w/w Gilsonite; 85% w/w AC-1/Nred(50/50) & 15% w/w Gilsonite; 82% w/w AC-1 & 18% w/w Gilsonite; 80% w/w Nred & 20% w/w Gilsonite; 84% w/w Suncor 300/400 & 16% w/w Gilsonite; and 85% w/w ASI Europe & 15% w/w Gilsonite.

25 . The asphalt paving composition of claim 1 , wherein the composition meets paving industry performance criteria over 86° C. or more.

26 . The asphalt paving composition of claim 25 , wherein the composition meets paving industry performance criteria over 92° C. or more.
