Patent number: 11851575Abstract: A method for generating a shingle roof coating is described. The method includes receiving an asphalt feedstock and separately proceeds to mix an elastomeric polymer and an asphalt flux to generate a first concentrate. The first concentrate is then heated separately from the asphalt feedstock. The method then mixes the first concentrate with the asphalt feedstock and heats the combined first concentrate and the asphalt feedstock to generate the shingle roof coating. The amount of elastomeric polymer in the first concentrate is adjusted based on the type of asphalt feedstock such that the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.Type: GrantFiled: May 24, 2021Date of Patent: December 26, 2023Assignee: ASPHALT SCIENCES LLCInventors: Joseph Randall Bruns, Hashem Hashemi, Moises Cisneros Rached

Patent number: 11459274Abstract: A method and system for generating a tire rubber asphalt compound is described. The method includes receiving an asphalt compound and heating the asphalt compound to approximately 320° F. to 420° F. The method then proceeds to add tire rubber to the asphalt compound. The asphalt compound and the scrap tire rubber are mixed for approximately 5 minutes to 360 minutes during heating to approximately 525° F. to 700° F. to generate the tire rubber asphalt compound. The tire rubber asphalt compound is then cooled.Type: GrantFiled: November 2, 2020Date of Patent: October 4, 2022Assignee: ASPHALT SCIENCES LLCInventors: Joseph Randall Bruns, Hashem Hashemi

Patent number: 11015085Abstract: An asphalt composition for use as a shingle roof coating is described. The asphalt composition includes a first asphalt feedstock and a first concentrate. The first concentrate includes an elastomeric polymer and an asphalt flux. The asphalt composition includes 0.5% to 6% by weight of the elastomeric polymer. The elastomeric polymer includes a styrenic block copolymer. The first concentrate includes 3% by weight to 25% by weight of the styrenic block copolymer. The first concentrate includes 3% by weight to 15% by weight of one of an ethylene polymer and an ethylene propylene copolymer. The first concentrate has a penetration of at least 100 dmm.Type: GrantFiled: April 20, 2020Date of Patent: May 25, 2021Assignee: ASPHALT SCIENCES LLCInventors: Joseph Randall Bruns, Hashem Hashemi, Moises Cisneros Rached

Patent number: 10626295Abstract: An asphalt composition suitable for use as a shingle roof coating is described. The asphalt composition comprises an oxidized asphalt feedstock and a first concentrate. The oxidized asphalt feedstock has a softening point greater than 205° F. and a penetration of less than 15 dmm. The first concentrate includes an elastomeric polymer and an asphalt flux. The asphalt composition includes 1.5% to 4.5% by weight of the elastomeric polymer.Type: GrantFiled: February 15, 2018Date of Patent: April 21, 2020Assignee: ASPHALT SCIENCES, LLC.Inventors: Joseph Randall Bruns, Hashem Hashemi, Moises Cisneros Rached

Patent number: 10214617Abstract: A method for generating a dissolving rubber compound in asphalt is described. The method includes receiving an asphalt compound and heating the asphalt compound to approximately 320° F. to 420° F. The method then proceeds to add a tire rubber compound to the asphalt compound. The asphalt compound and the tire rubber compound are mixed for approximately 5 minutes to 240 minutes. The dissolved rubber compound is generated by heating a mixture of the asphalt compound and the tire rubber to approximately 525° F.-700° F. The dissolved rubber compound is then cooled.Type: GrantFiled: October 3, 2016Date of Patent: February 26, 2019Assignee: ASPHALT SCIENCES, LLC.Inventors: Joseph Randall Bruns, Hashem Hashemi

Patent number: 9909031Abstract: A method and composition for generating a shingle roof coating is described. The method includes oxidizing an asphalt feedstock to a softening point greater than 205° F. and a penetration less than 15 dmm at 77° F. to generate an oxidized asphalt feedstock. The method then proceeds to mix an elastomeric polymer and an asphalt flux to generate a first concentrate. The first concentrate is then heated separately from the oxidized asphalt feedstock. The method then mixes the first concentrate with the oxidized asphalt feedstock and heats the combined first concentrate and the oxidized asphalt feedstock to generate the shingle roof coating. The amount of elastomeric polymer in the first concentrate is adjusted based on the type of asphalt feedstock such that the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.Type: GrantFiled: October 12, 2015Date of Patent: March 6, 2018Assignee: ASPHALT SCIENCES, LLCInventors: Joseph Randall Bruns, Hashem Hashemi, Moises Cisneros Rached
