Edwin Gresham Moore has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Modification of asphalt cement
    Patent number: 6743839
    Abstract: This invention is based upon the discovery that a polydiene rubber that is comprised of repeat units that are derived from a conjugated diene monomer and sulfur can be used to improved the force ductility, elastic recovery, toughness and tenacity of asphalt cement. The polydiene rubber that is comprised of repeat units that are derived from a conjugated diene monomer and sulfur also exhibits excellent compatibility with asphalt. The repeat units in the polydiene rubber that are derived from sulfur are in the backbone of the polymer. These repeat units that are derived from sulfur typically contain from 2 to 8 sulfur atoms (—Sn—). The subject invention more specifically relates to a modified asphalt cement which is comprised of (i) from about 90 weight percent to about 99 weight percent asphalt; (ii) from about 1 weight percent to about 10 weight percent of a polydiene rubber that is comprised of repeat units that are derived from a conjugated diene monomer and sulfur.
    Type: Grant
