In this paper a three step process is proposed for stabilizing thermal residues and bitumens. The process is based on the addition of phosphorus compounds such as phosphoric or polyphosphoric acid to thermal residues and bitumens (first step), and to the resulting utilization of the insoluble by-product for upgrading straight-run bitumens (second step), or for the preparation of stable polymer modified bitumens (third step)
