Zusammenfassung:	Asphalt compositions for roofing applications are provided, as well as filled asphalt material comprising the asphalt compositions and methods for making asphalt compositions and filled asphalt material. More particularly, the asphalt compositions comprise non-oxidized base asphalt; and a low molecular weight polyolefin present in an amount of from about 0.5 to about 15 wt % based on the total weight of the asphalt composition. The asphalt composition has a softening point from about 87.8 to about 160° C. (about 190 to about 320° F.), a penetration of greater than 12 deci-millimeters @ 25° C., as well as improved stain resistance and heat resistance.
