  • the sulfur is present as elemental sulfur and may, in some embodiments, include a mixture of sulfur aliotropes.
  • One source of elemental sulfur includes waste sulfur removed as part of hydrocarbon processing, such as sulfur produced from a Claus unit.
  • the base asphalt material can be a singular material or a blend of several base asphalts. All asphalts contain asphaltenes. Asphaltenes include clusters of large polycyclic aromatic molecules. The structure of asphaltenes may include, in no particular order or regularity, cycio-alkanes, eyclo-alkenes, and alkane and alkene chains extending from polycyclic molecules for up to 30 carbons (C30) in length. Asphaltenes can also have functional moieties that are capable of reacting with other materials.
  • Functional moieties include alcohols, carboxylic acids, ketones, phenols, amines, amides, sulfides, sulfoxides, sulfones, sulfonic acids, and porphyrin rings chelated with vanadium, nickel, and iron.
  • Asphaltenes can also have heterorganic aromatic rings part of their overall polycyclic structure, including benzothiophene, pyrrole and pyridine rings.
  • Asphalt is a colloidal dispersion of asphaltenes in a maitenes phase.
  • the maltenes phase which is more mobile than the asphaltene phase, include asphaltene resins, polar and non-polar aromatics, cyclic saturated hydrocarbons (e.g., naphthenes), and both straight and long-chain saturated hydrocarbons.
  • polar aromatics in the maltene phase tend to be the dispersing agent for the asphaltenes, interacting with polar functional groups that can exist on asphaltenes.

  • the polymer is an elastomer.
  • the polymer is a plastomer.
  • An elastomer is technically defined as a cross-linked, amorphous polymer that is above its glass transition (T g ) temperature; however, most of ordinary skill in the art consider elastomers to be either thermoplastic or thermoset polymers that when a load is applied it will yield and stretch with the load, and it will rebound to its original form when the load is released.
  • Classes of traditional elastomers include diene elastomers, saturated elastomers, thermoplastic elastomers and inorganic elastomers, including silicon and sulfur-based polymers. Elastomers enhance the elastic recover)' capacity of the asphalt binder, which makes the asphalt binder resistant to permanent deformation due to physical manipulation,
  • Unsaturated thermoplastic elastomers including styrene-butadiene-styrene (SBS) block copolymers, are known as useful polymers for inclusion in asphalt binder for modifying its thermal and physical properties. SBS is recognized for its performance- enhancing benefits in road paving applications.
  • An embodiment of the composition includes where the elastomer comprises an SBS block copolymer.
  • An embodiment of the composition includes where the elastomer consists essentially of the SBS block copolymer.
  • Cross-linking SBS can maintain most of the elasticity of the SBS block copolymer while providing improved temperature resistance.
  • Plastomers occupy a position between traditional poiyolefins and elastomers. Plastomers are a class of polymers that when a load is applied it will yield and stretch (not brittle fracture like a traditional polyolefin such as atactic polypropylene) and will remain in its elongated position when the load is released (unlike an elastomer). Plastomers typically also add the property of high-temperature stiffness similar to a traditional polyolefin, whereas elastomers will begin to flow at lower temperatures. Plastomers can mitigate the potential of permanent deformation and loss of integrity through long-term high temperature exposure, such as what a composition may encounter on roof tops and near appliances that radiate heat. Plastomers are thermoplastic in nature, and therefore will deform in a plastic or viscous manner at melt temperatures of the plastomer and becomes hard and stiff at temperatures below melt.
  • Examples of useful plastomers include long-chain branched poiyolefins, including low-density polyethylenes (LDPE); highly-branched poiyolefins, including linear low-density polyethylenes (LLDPE), ethylene/a-olefin(s) copolyniers/ieipolymers/teirapolymers, and propylene/a-olefm 0 ⁇ ] ⁇ 6 ⁇ 8 ⁇ 1 ⁇ 8 ⁇ 6 ⁇ ⁇ 1 ⁇ 8, where the a-olefin(s)include one or more C3..2 0 olefins, including propylene, butene, hexene, and octene, and the ethylene/propylene comprises at least 50% by weight of the copolymers/terpolymers/ tetrapolymers; ethylene butyl acrylates (EBA); and ethylene vinyl acetate (EVA).

  • An embodiment of the sulfur-extended plastomer asphalt binder composition includes where the plastomer is an ethylene vinyl acetate (EVA) polymer.
