ABSTRACT:
The present invention is an asphaltic composition which is useful as a roofing asphalt formulation and method of making this formulation. The composition includes about 39 to 99 percent by weight of oxidized asphalt and between 1 and about 8 percent oxidized polyethylene. It is preferred to use between about 0 to 40 percent of the saturant, which can be an unoxidized asphalt, to modify the viscosity of the formulation. There can be a filled asphaltic composition comprising about 40 percent by weight to about 99 percent by weight of the asphaltic composition and about 1 percent by weight to about 60 percent by weight of filler, which can be stone dust.
