Polymer modified asphalt for industrial applications

An industrial asphalt composition comprising a base asphalt, a hard PEN asphalt, a polymer modifier, and at least one wax, wherein the industrial asphalt composition includes 5 weight percent to 95 weight percent of the hard PEN asphalt and from 5 weight percent to 95 weight percent of the base asphalt, wherein the industrial asphalt composition is void of blown asphalts, and wherein the industrial asphalt composition has softening point which is within the range of 120° F. to 260° F., a penetration at 77° F. which is within the range of 12 dmm to 40 dmm, and a rotational viscosity which is within the range of 90 cP to 700 cP at 400° F.

A method for producing an industrial asphalt composition comprising:

• obtaining a partially blown asphalt or a hard PEN asphalt;
• obtaining an asphalt base selected from the group consisting of paving grade asphalts, flux grade asphalts, PEN grade asphalts, viscosity grade asphalts, aged residue grade asphalts, and combinations thereof;
• blending the partially blown asphalt or a hard PEN asphalt into an asphalt base which is selected from the group consisting of paving grade asphalts, flux grade asphalts, PEN grade asphalts, viscosity grade asphalts, and aged residue grade asphalts, wherein the asphalt base is not air blown, wherein the base asphalt is asphalt flux, wherein the partially blown asphalt or hard PEN asphalt is asphalt flux, wherein the industrial asphalt composition is void of naturally occurring asphalt, and wherein the industrial asphalt composition has softening point which is within the range of 120° F. to 260° F., a penetration at 77° F. which is within the range of 12 dmm to 40 dmm, and a rotational viscosity which is within the range of 90 cP to 700 cP at 400° F.
