  • Patent number: 10550267
    Abstract: A method of waterproofing or damp proofing a protected member having a surface with a sulfur-extended elastomer asphalt binder composition uses a sulfur-extended elastomer asphalt binder composition that includes elemental sulfur, an elastomer and an asphalt binder. The method includes the steps of combining the elastomer with the asphalt binder maintained at an elastomer mixing temperature such that an intermediate asphalt binder mixture forms, and combining elemental sulfur with the intermediate asphalt binder maintained at a sulfur mixing temperature such that the sulfur-extended elastomer asphalt binder composition forms. The method also includes the step of applying the sulfur-extended elastomer asphalt binder composition to the surface of the protected member such that the sulfur-extended elastomer asphalt binder composition contacts, adheres to and forms a layer upon the surface of the protected member. The asphalt binder composition is applied at a temperature no greater than 145° C.

  • Patent number: 9493633
    Abstract: The present invention generally relates to the discovery that a blend of linear and branched amide wax additives can be used to enhance the performance of asphalt binders and asphalt emulsion residues. In particular, high temperature properties of asphalt pavement can be improved while maintaining or improving low temperature properties. The additives also improve workability and lower processing temperatures for asphalt paving (e.g. warm mix) or for roofing. These amide wax additives can reduce the tracking of tack coats, by decreasing binder penetration and forming a non-tacky surface layer.

    Abstract: A method for making a modified polymer is characterized by re-capsulating the polymer via extrusion. A cross-linking agent is mixed with particles of synthetic rubber material to form a mixture which is then heated and delivered to an extrusion device. The extrusion device further heats the mixture and produces strands of modified polymer material which are cooled and pelletized to form small pellets of re-capsulated modified polymer. A partitioning or anti-blocking agent is added to the pellets to prevent re-agglomerization of the modified polymer. When mixed with asphalt for a sufficient period of time, a modified polymer asphalt is produced with enhanced rheological properties for high and low temperatures.

  • Publication number: 20130303666
    Abstract: An additive for a bitumen or polymer modified bitumen product, which is prepared by mixing together a sulphur-based product, a vulcanized rubber, for example, a waste vulcanized rubber, preferably a fatty acid, and a bitumen, is described. The use of this additive for preparing, with very limited gaseous emissions, elastomer-containing bituminous product is also described. Such use may be especially suitable for making bituminous coated material including, for example, asphalt concrete.

  • Publication number: 20130261233
    Abstract: A method of producing sulfur modified organosilane compounds that can be used in asphalt binders which method involves: combining together an organosilane or mixtures of organosilanes, a sulfide, a halogen acceptor and solvent to form a reaction mixture; and allowing the organosilane to react with the sulfide in the presence of a halogen acceptor to produce a sulfur modified organosilane compound. The sulfur modified organosilane compound can be introduced into a polymer modified or unmodified asphalt binder in which the sulfur modified organosilane compound reacts with components in the asphalt mixture to form a modified asphalt. The organosilanes used to produce the sulfur modified organosilanes can be from a source of waste products (such as Direct Product Residue) in which case the waste products can be reused in asphalt binders.
