ABSTRACT:
Asphalt fractions unsuitable for use in paving formulations because of their inhomogeneity (as reflected by their inability to pass the Oliensis Spot Test) can be used to make homogeneous asphaltic compositions (which pass the Oliensis Spot Test) by combining them with a propane precipitated asphalt and/or petrolene fraction. The latter fractions must have a polar aromatic content of at least 20%. Optionally up to 10% vacuum gas oil can also be added to the compositions. These upgraded asphaltic compositions have a polar aromatic content of at least 30% and are useful in paving formulations.
