  • Patent number: 10633540
    Abstract: It has been found that numerous benefits can be realized by air blowing asphalt in the presence of at least one highly saturated polymer, such as polyisobutylene, and a reactive polymer having glycidyl groups, such as an ethylene-glycidyl-acrylate. This allows for asphalt streams which would typically not be commercially viable for blowing into industrial asphalt that can be used in roofing products and a wide array of other applications. For instance, this technique can be used to air blow currently available paving grade asphalts into industrial asphalt for roofing products. Other potential benefits include shorter processing time (air blowing time), reduced emissions, and blown coatings with improved weatherability. In one embodiment of this invention asphalt is only partially air blown before adding the polymer to attain a product having desired characteristics for specific applications.

  • Patent number: 10344236
    Abstract: The present invention relates to a process for preparing fuel-in-water emulsions from oil refining residues, in both continuously or in batches, by adding an emulsifying agent to disperse the residual oil in water and facilitate its transportation. This process does not require the use of chemical substances like stabilizers or diluents for its preparation. The vacuum residue is not limited to specific characteristics and the water used, can be distilled, tap water or saltwater (seawater). The process requires low concentration of a non-ionic surfactant; and the emulsions obtained have proportions from 70 to 90% by weight of refining residues, 10 to 30% by weight of water and from 0.1 to 1% by weight of surfactant. The fuel-in-water emulsion is produced from oil refining residues, such as residues of atmospheric and vacuum distillation, heavy fuel oils and similar, and it is formed from 70 to 90% by weight of refining residues, 10 to 30% by weight of water and from 0.1 to 1% by weight of non-ionic surfactant.

Blocks A and B may individually represent (1) styrene and butadiene or (2) styrene and isoprene. The oil is a petroleum-based oil that both “softens” the asphalt and reduces the viscosity of the sealant composition. The wax may be a bis-stearamide wax. Additionally, the sealant composition may be reacted with elemental sulfur to crosslink the copolymer blend. The sealant composition seals at temperatures lower than conventional sealants and promotes the easy release of the shingle from a shingle bundle.

  • Publication number: 20150051322
    Abstract: This invention relates to asphalt compositions. The invention provides a sulfur rubber asphalt binder composition that includes a base asphalt having a softening point, elemental sulfur, and a crumb rubber material. The crumb rubber material is combined with the base asphalt and the elemental sulfur to create the sulfur rubber asphalt binder composition. The crumb rubber material is present in the sulfur rubber asphalt binder in an amount effective to increase the softening point as compared to the softening point of the base asphalt.

  • Publication number: 20150020711
    Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.

  • Patent number: 8937120
    Abstract: An additive for reclaiming asphalt of the present invention, which is obtained by adding straight asphalt to a mixture of a waste animal or vegetable oil and a waste mineral oil having a kinematic viscosity at 60° C. of 10 mm2/s to 40 mm2/s, mixing the materials, and heating the resultant mixture to remove an aromatic component. The additive for reclaiming asphalt can restore the physical properties of a deteriorated asphalt component to the same or greater extent than that of a conventional additive for reclaiming asphalt, and the additive has low content of components that may affect the environment or humans, and high fluidity at room temperature, and is available at an extremely low cost.

  • Publication number: 20150018460
    Abstract: The present invention relates to thermoplastic products. In particular, the present invention relates to systems and methods for providing a thermoplastic product that includes one or more recycled materials. In some non-limiting implementations, the recycled materials are selected from eggshells, slag, solid output from an incinerator, and/or asphalt shingles. In some cases, the recycled materials comprise between about 0.1% and about 95%, by weight, of the thermoplastic product. In some cases, the recycled materials have a particle size between about one inch and about 300 mesh. Other implementations are also described.

  • Patent number: 8926742
    Abstract: One embodiment provides a process for preparing an asphalt-coated crumb rubber composition that meets the specification set forth in ASTM D80-02 or deviations thereof which may be established by the specifying agency from time to time. The process generally comprises obtaining asphalt of different penetration grades, combining the asphalt of each grade with preselected chemicals to form separate premixed components, blending the premixed components together under predetermined conditions to form, upon curing, an asphalt-coated crumb rubber composition that meets certain physical requirements for asphalt-rubber binder (ARB), such as those set forth in ASTM D8-02. Advantageously, the resulting asphalt-coated crumb rubber composition not only meets the physical requirements of ARB used in road paving but also has improved dispersion of the rubber, such as dispersion of the rubber in an oil-in-water emulsion of an asphalt.
