ABSTRACT OF THE DISCLOSURE The present invention relates to an improved polyethylene modified asphaltic composition and a method for its manufacture. More specifically, when certain linear polyethylene compounds are added to an asphalt that is low in asphaltenes but relatively high in saturates, there results a composition which has excellent storage stability, phase compatibility and creep resistance relative to unmodified asphalts. The improved asphaltic composition is particularly well suited for use as a binder in paving materials and as a coating or saturant for roofing products.
