    Abstract: An asphalt composition includes asphalt, a non-epoxidized oil chosen from flux oils, bio oils, recycled motor oils, liquid plasticizers, and combinations thereof, and a polyolefin. The polyolefin has a weight average molecular weight (Mw) of from about 1,000 to about 20,000 g/mol, an optional acid number of from about 10 to about 50 mg KOH/g, an optional saponification number of from about 10 to about 100 mg KOH/g, and a density of from about 0.92 to about 1 g/cm3. The asphalt composition has a performance grade of PG (52 to 88) and (−22 to −40), wherein (52 to 88) is an average seven day maximum pavement design temperature in degrees Celsius and represents deformation resistance and (−22 to −40) is an average one day minimum pavement design temperature in degrees Celsius and represents thermal cracking resistance, each as determined using AASHTO M320.

    Abstract: 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.

    Abstract: Asphalt adhesive compositions and methods of producing the same are provided. In an exemplary embodiment, an asphaltic adhesive useful for self-adhering membranes includes asphalt at from about 40 to about 70 weight percent, based on a total weight of the adhesive. The adhesive also includes a low molecular weight (LMW) polyolefin at from about 1 to about 10 weight percent, based on the total weight of the adhesive. The LMW polyolefins have a weight average molecular weight (Mw) of from about 500 to about 20,000 Daltons. The adhesive has an aged peeling strength greater than an aged peeling strength of a comparable comparison adhesive, wherein the comparison adhesive includes from about 40 to about 70 weight percent asphalt but is free of a LMW polyolefin, as determined by Guobiao recommended (GB/T) 328.20-2007 in specification Guobiao (GB) 23441-2009 (self-adhering polymer modified bituminous waterproof sheet.)
