  • Patent number: 7901563
    Abstract: The present invention relates to a method for preparing an industrial asphalt comprising (1) heating an asphalt flux to a temperature which is within the range of about 400° F. (204° C.) to 550° F. (288° C.) to produce a hot asphalt flux, (2) sparging an oxygen containing gas through the hot asphalt flux for a period of time which is sufficient to increase the softening point of the asphalt flux to a value of at least 100° F. (38° C.), to produce an underblown asphalt composition; and (3) mixing a sufficient amount of a polyphosphoric acid throughout the underblown asphalt composition while the underblown asphalt composition is maintained at a temperature which is within the range of 200° F. (93° C.) to 550° F. (288° C.) to attain a softening point which is within the range of 185° F. (85° C.) to 250° F. (121° C.) and a penetration value of at least 15 dmm at 77° F. (25° C.) to produce the industrial asphalt.

  • Patent number: 7900266
    Abstract: It has been unexpectedly found that the solvent extracted aromatic cut of heavy vacuum gas oil can be oxidized to produce an adhesive composition that has all the needed attributes of a self seal adhesive for asphalt roofing shingles. This adhesive composition does not require any volatile organic solvents and is accordingly environmentally friendly. It does not contain any asphalt or polymers and will not phase separate. Thus, it offers excellent long term stability. Additionally, it is made by the simple oxidation of the solvent extracted aromatic cut of heavy vacuum gas oil and is accordingly relatively inexpensive. The subject invention more specifically reveals an asphaltic roofing shingle comprising a back surface and an exposure surface, wherein the back surface is covered with an oxidized solvent extracted aromatic cut of heavy vacuum gas oil.
