  • Methods and systems for manufacturing modified asphalts
    Patent number: 8377285
    Abstract: Methods and systems for efficiently manufacturing modified asphalt materials include agitating a base asphalt at a high shear rate using an in-line mixer while simultaneously exposing the asphalt to oxygen by blowing an oxygen-containing gas at a high gas flow rate through openings in the in-line mixer and heating the asphalt at an elevated temperature.
    Type: Grant
    Filed: March 14, 2011
    Date of Patent: February 19, 2013
    Assignee: Asphalt Technology LLC.
    Inventors: Michael V. Burris, Bryan B. Burris, Hossein Ajideh, Andrew Clayton
  • Methods and systems for modifying asphalts
    Patent number: 8252168
    Abstract: A method for modifying asphalt comprises blowing an oxygen-containing gas through a base asphalt at a high gas flow rate while simultaneously agitating the base asphalt at a high shear rate and at an elevated temperature for a period of time that is effective to substantially improve at least two paving properties of the base asphalt. In preferred embodiments, modified asphalts are produced having both substantially improved rutting resistance and substantially improved fatigue resistance as compared to the base asphalt.
