Polyolefin asphalt modifiers, methods of modifying asphalt, asphalt compositions and methods of making
An asphalt additive comprising a primary rheology modifying component and a secondary rheology modifying component, and asphalt compositions and products having such additive incorporated therein. The primary rheology modifying component is generally a polymer, and the secondary rheology modifying component may comprise a petroleum micro-wax.
1. An asphalt comprising:
a first component comprising a petroleum asphalt; and,
a second component comprising particles formed from a melted mixture of a resin and a binder;
wherein, the second component is dispersed within the first component;
wherein the resin is polypropylene homopolymer; and,
wherein the binder comprises a terpolymer comprising at least one of glycidyl functionality, glycidyl acrylate functionality, or epoxide functionality.
2. The asphalt of claim 1 , wherein the binder comprises a terpolymer comprising an ethylene-butyl acrylate-glycidyl methacrylate.
3. A method of treating a petroleum asphalt, the method comprising:
contacting a petroleum asphalt with particles formed from a melted mixture of a resin component and a binder component to form a treated asphalt,
wherein the resin is polypropylene homopolymer; and,
wherein the binder comprises a terpolymer comprising at least one of glycidyl functionality, glycidyl acrylate functionality, or epoxide functionality.
4. The method of claim 3 , wherein the binder comprises a terpolymer comprising an ethylene-butyl acrylate-glycidyl methacrylate.
5. An asphalt comprising:
a first component comprising a petroleum asphalt;
a second component comprising particles formed from a melted mixture of a resin and a binder; and,
a third component dispersed in the asphalt selected from the group consisting of ground tire rubber and polymers of styrene and butadiene,
wherein the resin is polypropylene homopolymer; and,
wherein the binder comprises a terpolymer comprising at least one of glycidyl functionality, glycidyl acrylate functionality, or epoxide functionality.
6. The method of claim 5 , wherein the binder comprises a terpolymer comprising an ethylene-butyl acrylate-glycidyl methacrylate.
7. A method of modifying a petroleum asphalt, the method comprising: combining the petroleum asphalt with a first component and a second component,
wherein the first component comprises particles formed from a melted mixture of a resin and a binder; and, the second component is selected from the group consisting of ground tire rubber and polymers of styrene and butadiene,
wherein the resin is polypropylene homopolymer; and,
wherein the binder comprises a terpolymer comprising at least one of glycidyl functionality, glycidyl acrylate functionality, or epoxide functionality.
8. The method of claim 7 , wherein the binder comprises a terpolymer comprising an ethylene-butyl acrylate-glycidyl methacrylate.
