Recycled reclaimed asphalt pavement
View Patent ↗The present disclosure generally relates to formulations of, and methods of making and using, recycled reclaimed asphalt pavement.
1. A formulation of recycled reclaimed asphalt pavement comprising:
a reclaimed asphalt pavement;
an emulsion at less than 1.25% by weight of the reclaimed asphalt pavement; and
water.
2. The formulation of claim 1 , wherein the reclaimed asphalt pavement is reprocessed asphalt paving materials.
3. The formulation of claim 1 , wherein the reclaimed asphalt pavement and emulsion are combined to form an emulsion-coated reclaimed asphalt pavement.
4. The formulation of claim 1 , wherein the emulsion is a polymer-modified cationic slow setting emulsified asphalt with a solvent-free rejuvenator.
5. The formulation of claim 1 , wherein the water is 2-2.5% greater than surface saturation of the reclaimed asphalt pavement.
6. The formulation of claim 1 , wherein the reclaimed asphalt pavement passes through a 1¼-inch sieve.
7. A method of making recycled reclaimed asphalt pavement comprising:
fractionating a reclaimed asphalt pavement to form a fractionated reclaimed asphalt pavement; and
combining the fractionated reclaimed asphalt pavement, an emulsion at less than 1.25% by weight of the reclaimed asphalt pavement, and water.
8. The method of claim 7 , wherein the reclaimed asphalt pavement is reprocessed asphalt paving materials.
9. The method of claim 7 , wherein the fractionated reclaimed asphalt pavement passes through a 1¼-inch sieve.
10. The method of claim 7 , wherein the combining of the fractionated reclaimed asphalt pavement and the emulsion forms an emulsion-coated fractionated reclaimed asphalt pavement.
11. The method of claim 7 , wherein the combining is in a pug mill.
12. The method of claim 7 , wherein the emulsion is a polymer-modified cationic slow setting emulsified asphalt with a solvent-free rejuvenator.
13. The method of claim 7 , wherein the water is 2-2.5% greater than surface saturation of the reclaimed asphalt pavement.
14. The method of claim 7 , further comprising storing the recycled reclaimed asphalt pavement in a stockpile for more than six months.
15. A method of using recycled reclaimed asphalt pavement comprising:
applying a recycled reclaimed asphalt pavement comprising a reclaimed asphalt pavement that has been fractionated, an emulsion at less than 1.25% by weight of the reclaimed asphalt pavement, and water to a surface; and
compacting the recycled reclaimed asphalt pavement on the surface.
16. The method of claim 15 , wherein the reclaimed asphalt pavement is reprocessed asphalt paving materials.
17. The method of claim 15 , wherein the reclaimed asphalt pavement passes through a 1¼-inch sieve.
18. The method of claim 15 , wherein the emulsion is a polymer-modified cationic slow setting emulsified asphalt with a solvent-free rejuvenator.
19. The method of claim 15 , wherein the water is 2-2.5% greater than surface saturation of the reclaimed asphalt pavement.
20. The method of claim 15 , further comprising storing the recycled reclaimed asphalt pavement for more than six months before applying it to a surface.
21. The method of claim 15 , wherein the recycled reclaimed asphalt pavement is applied as a wearing course.
22. The method of claim 15 , wherein the compacting is by a pneumatic roller.
23. The method of claim 15 , wherein the compacting is by a pneumatic roller followed by a finish roller.
24. The method of claim 15 , further comprising adding a fog seal emulsion.
25. A kit comprising:
a reclaimed asphalt pavement;
an emulsion at less than 1.25% by weight of the reclaimed asphalt pavement; and
instructions for combining or using the reclaimed asphalt pavement and emulsion.
