  • Patent number: 6863724
    Abstract: Sulfur, useable in as an additive to asphalt in the preparation of asphalt binders can be plasticized by addition of carbon and further treated with amyl acetate. This plasticized sulfur can be formed into solid particles and then added to asphalt as either a minority or majority component to create desired paving binder compositions. The solid plasticized sulfur has non-stick non-flow properties within a wide range of ambient temperatures, and it can be stored solid for subsequent use in paving applications.
    Type: Grant
    Filed: August 8, 2002
    Date of Patent: March 8, 2005
    Assignee: Shell Canada Limited
    Inventors: William R. Bailey, Norm D. Pugh
  • Patent number: 6824600
    Abstract: Solid, low-cost paving binder prepared by admixing sulfur, paving grade asphalt (AC) asphalt, and a siliceous filler such as fly ash and silica material, and solidifying the product into preferably flaked, pellet or pastille forms. Carbon black is another possible ingredient of the paving binder. The solid paving binder has non-sick non-flow properties within a wide range of ambient temperatures, and it can be stored solid for subsequent use in paving applications. Properties such as the color, radiation-resistance, and odor of the paving binder can be controlled in the manufacturing process.
