摘要： 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° F. (204° C.) to 550° F. (288° 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° F. (38° 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° F. (93° C.) to 550° F. (288° C.) to attain a softening point which is within the range of 185° F. (85° C.) to 250° F. (121° C.) and a penetration value of at least 15 dmm at 770° F. (25° C.) to produce the industrial asphalt.
