Reinforcement composition and method thereof
View Patent ↗The present invention relates generally to a reinforcement composition and a method of reinforcing an asphalt cement concrete composition. The reinforcement composition includes a core and an outer container. The core includes a plurality of fibers, and the outer container includes a polyolefin selected from the group consisting of polyethylene, polypropylene, and mixtures thereof.
1. A reinforcement composition comprising a core and an outer container, the core contained within the outer container, the core comprising a plurality of fibers, the outer container comprising a polyolefin selected from the group consisting of polyethylene, polypropylene, and mixtures thereof, and the outer container constructed such that when said outer container is heated to a specified temperature, the plurality of fibers is released from said outer container.
2. The reinforcement composition of claim 1 , wherein the plurality of fibers is selected from the group consisting of synthetic fibers, natural fibers, and mixtures thereof.
3. The reinforcement composition of claim 2 , wherein the synthetic fibers are selected from the group consisting of polymer fibers, aramid fibers, and mixtures thereof.
4. The reinforcement composition of claim 3 , wherein the polymer fibers are selected from the group consisting of polyolefin fibers, polyamide fibers, polyvinyl-chloride fibers, and mixtures thereof.
5. The reinforcement composition of claim 4 , wherein the polyolefin fibers are selected from the group consisting of polypropylene fibers, polyethylene fibers, and mixtures thereof.
6. The reinforcement composition of claim 1 , wherein the plurality of fibers are each or together configured in a predetermined number of twists.
7. The reinforcement composition of claim 1 , wherein the outer container further comprises amine.
8. The reinforcement composition of claim 1 , wherein the outer container further comprises a plurality of fibers.
9. The reinforcement composition of claim 1 , wherein the plurality of fibers is selected from the group consisting of fibers that are meltable in an asphalt material, fibers that are non-meltable in an asphalt material, and mixtures thereof.
10. The reinforcement composition of claim 1 , wherein the outer container is dispersible.
11. The reinforcement composition of claim 10 , wherein the outer containment material is dispersible by melting.
12. The reinforcement of composition of claim 3 , wherein the plurality of fibers includes a blend of aramid fibers and polyolefin fibers.
13. A reinforced asphalt composition, comprising:
a reinforcement component, comprising:
a core comprising a plurality of fibers; and
an outer container which encompasses the core, the outer container constructed such that when said outer container is heated to a specified temperature, the plurality of fibers are released from said outer container;
and
an asphalt component, comprising:
aggregate; and
binder.
