Abstract
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.
Claims33
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 selected from the group consisting of reactive elastomeric terpolymers, polymers having glycidyl functionality, polymers having glycidyl acrylate functionality, and polymers having epoxide functionality;
- and,
- wherein the binder is selected from the group consisting of polyethylene by-product waxes, petroleum micro waxes, Fischer-Tropsch hard wax, Trimidad Lake asphalt (TLA), gilsonite, and montan waxes.
4 more elements
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 selected from the group consisting of reactive elastomeric terpolymers, polymers having glycidyl functionality, polymers having glycidyl acrylate functionality, and polymers having epoxide functionality;
- and,
- wherein the binder is selected from the group consisting of polyethylene by-product waxes, petroleum micro waxes, Fischer-Tropsch hard wax, Trimidad Lake asphalt (TLA), gilsonite, and montan waxes.
1 more element
An asphalt comprising:
- a first component comprising a petroleum asphalt;
- a second component dispersed in the asphalt 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 selected from the group consisting reactive elastomeric terpolymers, polymers having glycidyl functionality, polymers having glycidyl acrylate functionality, and polymers having epoxide functionality;
- and,
- wherein the binder is selected from the group consisting of polyethylene by-product waxes, petroleum micro waxes, Fischer-Tropsch hard wax, Trimidad Lake asphalt (TLA), gilsonite, and montan waxes.
4 more elements
A method of modifying a petroleum asphalt, the method comprising:
- combining the petroleum asphalt with a first component and a second component to form a modified asphalt,
- 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 selected from the group consisting of reactive elastomeric terpolymers, polymers having glycidyl functionality, polymers having glycidyl acrylate functionality, and polymers having epoxide functionality;
- and,
- wherein the binder is selected from the group consisting of polyethylene by-product waxes, petroleum micro waxes, Fischer-Tropsch hard wax, Trimidad Lake asphalt (TLA), gilsonite, and montan waxes.
3 more elements
A method of modifying a petroleum asphalt, the method comprising:
- combining the petroleum asphalt with an additive to form a modified asphalt,
- wherein the additive comprises ground tire rubber and resin, wherein the resin is selected from the group consisting of reactive elastomeric terpolymers, polymers having glycidyl functionality, polymers having glycidyl acrylate functionality, and polymers having epoxide functionality.
