- and,
- petroleum based asphalt, wherein the weight ratio of asphalt to tall oil material is in the range of about 1:99 to about 99:1.
A product comprising:
- Aggregate, and
- a binder comprising:
- a tall oil material having a softening point in the range of 75 F to 400 F, a Needle Penetration value (0.1 mm) at 25 C of at least 1, a Rotational Viscosity at 275 F in the range of 650 cps to 8,000 cps, and a water solubility of less than 10 percent;
- and,
- petroleum based asphalt, wherein the weight ratio of asphalt to tall oil material is in the range of about 1:99 to about 99:1,
- wherein the aggregate is dispersed throughout the binder.
A method of modifying a petroleum based asphalt comprising:
- contacting the petroleum based asphalt with at least one modifier comprising a tall oil material to form a modified asphalt, wherein the tall oil component has a softening point in the range of 75 F to 400 F, a Needle Penetration value (0.1 mm) at 25 C of at least 1, a Rotational Viscosity at 275 F in the range of 650 cps to 8,000 cps, and a water solubility of less than 10 percent, and wherein the weight ratio of petroleum based asphalt and tall oil material is in the range of about 1:99 to about 99:1.
A method of making an asphalt product comprising:
- Forming a mixture comprising aggregate, a petroleum based asphalt and a tall oil material, to form an asphalt product, wherein the tall oil material has a softening point in the range of 75 F to 400 F, a Needle Penetration value (0.1 lm) at 25 C of at least 1, a Rotational Viscosity at 275 F in the range of 650 cps to 8,000 cps, and a water solubility of less than 10 percent, and wherein the weight ratio of petroleum based asphalt and tall oil material is in the range of about 1:99 to about 99:1.
An tall oil asphalt product comprising:
- A tall oil material;
- and,
- at least one polymer selected from the group consisting of Latex Emulsion, Styrene Butadiene Styrene, natural or synthetic Styrene Butadiene Rubber, Styrene Ethylene Butadiene Styrene, Polypropylene (polymer or wax), Polyethylene (polymer or wax), Atactic-Polypropylene, Fischer-Tropsch Wax, Microcrystalline Wax, Crumbed Tire Rubber, Ethylene Vinyl Acetate, Terpolymers, Montan, Epoxy Resins, Petroleum Wax, PTFE;
- wherein the weight ratio of tall oil material to polymer is in the range of about 1:99 to about 99:1,
- wherein the product is free of petroleum based asphalt;
- and wherein the product has a softening point in the range of 75 F to 400 F, a Needle Penetration value (0.1 mm) at 25 C of at least 1, a Rotational Viscosity at 275 F in the range of 650 cps to 8,000 cps, and a water solubility of less than 10 percent.
