An integrated process that is operated to create both a higher value pipelineable crude and a higher value carbon fiber product from a lower value common heavy hydrocarbon feedstock where the feedstock is processed in a thermal reactor followed by a solvent deasphalting unit with the liquids being gathered and processed to reduce olefins for pipeline transport and the solids are processed to generate a marketable carbon fiber product with any gases generated throughout the entire process reused in the process or sold.

A bitumen polymer additive comprises a base of tire rubber crumbs in the amount of about 70 to about 90 percent by weight of tire rubber crumbs sized about 14 mesh or smaller. Added to that base is about 0.5 to about 5 percent by weight of a benzothiazole-based devulcanizing agent, about 0.3 to about 3 percent by weight of a C.sub.14-C.sub.18 heavy metal soap such as a zinc stearate, about 0.1 to about 3 percent by weight of an antiozonant, and about 0.1 to about 20 percent of a plasticizer such as a heavy oil. The additive polymer is used for producing an asphalt of superior quality, including lower initial viscosity and improved wear resistance.
