  • Pre-swelled ground tire rubber and methods of making and using the same
    Patent number: 9458320
    Abstract: Disclosed herein are compositions and methods relating to rubber compositions, comprising crumb rubber and a maltene-like oil, which provides simultaneous rut, crack, moisture, and temperature resistance in both dense grade and gap grade paving mixtures. Also disclosed are methods of producing the rubber compositions, and methods of using the same.
    Type: Grant
    Filed: September 18, 2013
    Date of Patent: October 4, 2016
    Assignees: Innovative Polymer Solutions, Inc., Polymer Consultants, Inc.
    Inventors: Peter C. Blyth, David L. Bangs
  • Rubber-containing bituminous mixtures and methods for making and using same
    Patent number: 9018279
    Abstract: Disclosed are methods for producing rubber-containing bituminous mixtures by pressurizing mixtures of bituminous materials, crumb rubber, and one or more suspension agents with a gas, and then reducing the pressure, creating bubbles of the gas in the mixture. Also disclosed are methods of introducing gas into such mixture by rapid mixing. Mixtures produced by the disclosed methods, such as rubber-containing asphalt mixtures and paving compositions thereof, and their use are also disclosed.

  • Method and System for Removing Polychlorinated Biphenyls from Plastics
    Publication number: 20100013116
    Abstract: Removing PCBs from recycled plastic materials. A reactor can volatilize the PCBs from interior portions of the plastic materials under pressure conditions below atmospheric pressure and temperatures sufficient to melt the plastic material. The reactor typically includes agitation that exposes the plastic material to the atmosphere within the reactor to promote the volatilization of the PCBs.
