  • Frictionally stable emulsions
    Patent number: 4017446
    Abstract: Incorporation of an elastomer into asphalt is achieved by treating the asphalt pavement with an emulsion having an external water phase and an oil phase containing a dissolved elastomer, the oil preferably being an aromatic oil having an aromatic content of at least 50 percent and a viscosity below 50 SUS at 210.degree. F (99.degree. C), the oil being mutually compatible with the asphalt and the elastomer.
    Type: Grant
    Filed: February 10, 1975
    Date of Patent: April 12, 1977
    Assignee: Phillips Petroleum Company
    Inventor: Pat F. Rion
  • Stable emulsions
    Patent number: 3936406
    Abstract: Control of the pH of an elastomer-containing emulsion concentrate having an external water phase and an oil phase containing a dissolved elastomer, the oil preferably being an aromatic oil having an aromatic content of at least 50 percent and a viscosity below about 50 SUS at 210.degree. F., within the range of a pH of 1 to 3.5, results in an emulsion concentrate system having improved storage stability. Such an emulsion concentrate system can be let down with water to form a frictionally stable emulsion system useful in the treating of asphalt pavements.
