    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 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.)
