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/cm. The asphalt composition has a performance grade of PG (52 to 88) and (&#x2212;22 to &#x2212;40), wherein (52 to 88) is an average seven day maximum pavement design temperature in degrees Celsius and represents deformation resistance and (&#x2212;22 to &#x2212;40) is an average one day minimum pavement design temperature in degrees Celsius and represents thermal cracking resistance, each as determined using AASHTO M320.

Asphalt compositions and methods of forming the same

Methods for reducing asphalt pavement thickness are provided. A method for producing thin asphalt pavement includes combining a base asphalt, an oxidized polyolefin, and an aggregate to form an asphalt paving material. A layer of the asphalt paving material is deposited on a substrate layer and compacted to a thickness.

Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139&#xb0; C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.

A non-blown roofing grade bitumen composition comprising bitumen feedstock, polyolefin having a molecular weight of from about 800 to about 50,000 g/mol, and optionally one or more additives, wherein the softening point of the composition is above 70&#xb0; C. as determined according to method ASTM D36 and the penetration of the composition is at least about 12 dmm at 25&#xb0; C. as determined according to method ASTM D5. A method of making the same.

Bitumen compositions and methods of making

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&#xb0; C. (about 190 to about 320&#xb0; F.), a penetration of greater than 12 deci-millimeters @ 25&#xb0; C., as well as improved stain resistance and heat resistance.

Asphalt binder compositions are provided comprising asphalt and a polymer blend, wherein the polymer blend comprises oxidized high density polyethylene and another polymer chosen from: maleated polypropylene, polyethylene homopolymer, high crystallinity polyethylene, and combinations thereof. Also provided are paving and roofing materials comprising the aforesaid asphalt binder compositions and an aggregate material. Methods for making and using the asphalt binder compositions are also provided.

Asphalt binder compositions and methods to make and use same

An asphalt paving material comprises an asphalt binder present in an amount of from about 3 to about 8 weight percent of the asphalt paving material. The asphalt binder comprises base asphalt and oxidized polyolefin that is present in an amount of from about 0.25 to about 10 weight percent of the base asphalt. Aggregate is present in an amount of about 92 to about 97 weight percent of the asphalt paving material. The oxidized polyolefin effectively adheres the asphalt binder to the aggregate so as to resist stripping of the asphalt binder from the aggregate caused by moisture.

Asphalt paving materials and methods for making the same

The present invention relates to a method for preparing an industrial asphalt comprising (1) heating an asphalt flux to a temperature which is within the range of about 400&#xb0; F. (204&#xb0; C.) to 550&#xb0; F. (288&#xb0; C.) to produce a hot asphalt flux, (2) sparging an oxygen containing gas through the hot asphalt flux for a period of time which is sufficient to increase the softening point of the asphalt flux to a value of at least 100&#xb0; F. (38&#xb0; C.), to produce an underblown asphalt composition; and (3) mixing a sufficient amount of a polyphosphoric acid throughout the underblown asphalt composition while the underblown asphalt composition is maintained at a temperature which is within the range of 200&#xb0; F. (93&#xb0; C.) to 550&#xb0; F. (288&#xb0; C.) to attain a softening point which is within the range of 185&#xb0; F. (85&#xb0; C.) to 250&#xb0; F. (121&#xb0; C.) and a penetration value of at least 15 dmm at 77&#xb0; F. (25&#xb0; C.) to produce the industrial asphalt.
