Patent number: 7241821Abstract: A method is provided for improving high temperature performance grade properties of polymer-modified, vulcanized asphalt by treating an asphalt cement under mild oxidizing conditions sufficient to provide a change in viscosity per hour as measured at 140° C. of less than about 500 poises per hour, of said asphalt cement, adding 1 wt. % to 10 wt. % of a polymer based on weight of said asphalt cement, and vulcanizing the polymer-containing asphalt cement. The invention further relates to asphalt compositions thus made and paving compositions containing these asphalt compositions.Type: GrantFiled: August 10, 2004Date of Patent: July 10, 2007Assignee: Marathon Ashland Petroleum LLCInventors: Roger E.

Patent number: 6153004Abstract: A sulfur in oil in asphalt blend is disclosed. A polymer-free slurry of solid, elemental, sulfur in liquid oil is used to add sulfur to asphalt. Addition of a slurry of solid sulfur in oil, or oil containing sulfur compounds, permits rapid and effective dispersion of the sulfur component in the asphalt. Uneven mixing, which can occur when sulfur is separately added as a solid, or in molten forms to the asphalt, is avoided. The method is safer because formation of explosive clouds of sulfur dust is avoided.Type: GrantFiled: December 17, 1999Date of Patent: November 28, 2000Assignee: Marathon Ashland Petroleum LLCInventor: Roger E. Hayner

Patent number: 6136898Abstract: A method is provided for improving high temperature performance grade properties of unblown asphalt by i) heating an asphalt cement to 200.degree. F. to 500.degree. F. (93.degree. C. to 260.degree. C.), ii) adding 0.1 wt. % to 10 wt. % ethylene-vinyl acetate copolymer based on weight of said asphalt cement to the heated asphalt cement, iii) adding 0.05 wt. % to 1.0 wt. % phosphorus-containing acid, e.g., polyphosphoric acid, based on weight of said asphalt cement and iv) mixing the resulting blend, thereby providing an unblown asphalt composition of greater useful temperature index (UTI). The invention further relates to asphalt compositions thus made and paving compositions containing these asphalt compositions.Type: GrantFiled: June 15, 1999Date of Patent: October 24, 2000Assignees: Marathon Ashland Petroleum LLC, Ashland Inc.Inventors: Roman Loza, Laurence G. Dammann, Roger E. Hayner, Patricia K. Doolin

Patent number: 6133351Abstract: A sulfur in oil in asphalt and polymer blend is disclosed. An asphalt and polymer blend is first prepared and then a slurry of solid sulfur in liquid oil added. Addition of a slurry of solid sulfur in oil or oil containing sulfur compounds, permits rapid and effective uniform dispersion of the sulfur component in the asphalt/polymer blend. Uneven mixing, which can occur when sulfur is separately added as a solid to the asphalt blend, is avoided. Polymer use is optimized because polymer matrix development (digestion/swelling) can be completed before cross-linking occurs. The method is safer because formation of explosive clouds of sulfur dust is avoided.Type: GrantFiled: December 16, 1999Date of Patent: October 17, 2000Assignee: Marathon Ashland Petroleum LLCInventor: Roger E. Hayner

Patent number: 6057390Abstract: A method is provided for improving high temperature performance grade properties of asphalt which comprises i) heating an asphalt cement to 200 to 500.degree. F. (93 to 260.degree. C.), ii) adding 1 to 10 wt. % crosslinkable polymer, e.g., styrene-butadiene-styrene triblock copolymer based on weight of said asphalt cement, iii) adding a useful temperature index (UTI) improving amount of dioxime(s) of 1,4-benzoquinone and its derivatives and optionally, free radical initiator, e.g., organic peroxide, and iv) mixing the resulting blend, thereby providing a paving asphalt having a greater useful temperature index (UTI) than a corresponding blend to which no dioxime is added. The invention further relates to asphalt compositions thus made and paving compositions containing these asphalt compositions.Type: GrantFiled: June 15, 1999Date of Patent: May 2, 2000Assignees: Ashland Inc., Marathon Ashland Petroleum LLCInventors: Roman Loza, Laurence G. Dammann, Roger E. Hayner, Patricia K. Doolin

Patent number: 6027557Abstract: Paraffinic fluxing components, e.g., paraffinic base stocks such as neutral oils or foots oil, can be added to asphalt composition and the resulting blend oxidized, e.g., by blowing, to improve low temperature properties at low addition rates (e.g., oil 1-5 wt. %). The resulting asphalt compositions exhibit important improvements in low temperature properties, resistance to thermal cracking and expanded useful temperature range.Type: GrantFiled: June 30, 1998Date of Patent: February 22, 2000Assignee: Marathon Ashland Petroleum LLCInventor: Roger E. Hayner

Patent number: 6001162Abstract: A method is provided for preparing asphalt composition, e.g., solvent deasphalting (SDA)-produced asphalt composition comprising a mixture containing SDA bottoms with or without vacuum tower bottoms and lube plant extract, which method comprises treating the asphalt composition with 0.05 to 0.5 wt % reactive sulfur under conditions sufficient to improve rheological properties of said composition as measured by increased complex shear modulus relative to a corresponding untreated mixture. The invention further relates to such asphalt composition and paving composition containing same.Type: GrantFiled: July 17, 1997Date of Patent: December 14, 1999Assignee: Marathon Ashland Petroleum LLCInventors: Roger E. Hayner, David P. Wesley

Patent number: 5911817Abstract: Mineral lubricant base oils (e.g., neutral oils) can be added to asphalt composition to improve low temperature properties at low addition rates (e.g., oil 1-5%). Rerefined oils (boiling above about 177.degree. C. (350.degree. F.)) have the same properties as virgin mineral lubricant base oils, but most rerefmed oils are too dark in color to be used as lube oil base stocks. Their use in asphalt would be ideal as color is not a problem and they are much cheaper in cost than virgin base oils. This can permit disposing of rerefined motor oil. The resulting asphalt compositions exhibit important improvements in low temperature properties, resistance to thermal cracking and expanded useful temperature range.Type: GrantFiled: October 15, 1998Date of Patent: June 15, 1999Assignee: Marathon Ashland Petroleum LLCInventor: Roger E Hayner

Patent number: 5728291Abstract: In this combination process, solvent deasphalting (SDA) concentrates metals in the bottoms product which can be blended to asphalt as a product or for sending to the Calderon or similar process and outputs a high carbon (4+ concarbon) feed which is readily cracked to valuable transportation fuels by an RCC.RTM. cracking unit (or a conventional FCC with catalyst cooler and oxygen to the regenerator so that it acts as an RCC). The Rose process can be used instead of SDA to save utilities. By this invention, heavy crude can be converted to valuable transportation fuels and asphalt product, and catalyst make-up can be sharply reduced in the RCC or FCC unit because metals (asphaltenes and porphyrins) are removed before cracking. Novel asphalt compositions and blending are also disclosed. Asphalt from the SDA can preferably be blended with lube plant extract (or other aromatic extract) to produce specific asphalts meeting new SHRP specifications for paving.Type: GrantFiled: February 2, 1996Date of Patent: March 17, 1998Assignee: Ashland Inc.Inventors: Charles B. Miller, Howard F. Moore, David P. Wesley, Robert H. Wombles, Carlton H. Jewitt, Roger E. Hayner, Willian H. Gilkerson, Sr., Charles R. Gannon
