  • Paving asphalt
    Patent number: 4647313
    Abstract: An improved asphaltic cement particularly suited for paving applications and a method for producing same are described. The asphalt comprises between about 80 and about 99 wt. % of a residuum having a viscosity of at least 6000 poise at 60.degree. C. and about 1 to about 20 wt. % of a fatty acid.
    Type: Grant
    Filed: October 17, 1985
    Date of Patent: March 3, 1987
    Assignee: Exxon Research and Engineering Company
    Inventor: Dominick Clementoni
  • Air-treated propane-precipitated asphalt
    Patent number: 4283230
    Abstract: Propane-precipitated asphalt is contacted with a stream of air at 200.degree. C. and above to increase the softening point of the asphalt. The resulting asphalt base, having a softening point of about 65.degree.-300.degree. C., is then blended with 5-60 weight percent liquid sulfur-treated petroleum fraction, having an equivalent atmospheric boiling point range of 370.degree.-500.degree. C., to yield paving grade quality asphalt cement composition.
    Type: Grant
    Filed: January 10, 1980
    Date of Patent: August 11, 1981
    Assignee: Exxon Research & Engineering Co.
    Inventors: Dominick Clementoni, Luke W. Corbett
  • Sulfur-treated propane-precipitated asphalt
    Patent number: 4283231
    Abstract: Propane-precipitated asphalt is heated with 1-15 wt. % elemental sulfur at 140.degree. to 300.degree. C. until hydrogen sulfide evolution ceases. The sulfur-treated asphalt base material having an increased softening point of about 65.degree.-300.degree. C., is blended with 5-60 wt. % liquid petroleum fraction, such as vacuum gas oil or extract oil, having an equivalent atmospheric boiling point of 370.degree.-500.degree. C., to yield a quality paving grade asphalt cement composition meeting ASTM standards.
