Asphalt is a natural constituent of crude oils and is presently produced from the distillation residues of refining feedstocks. The asphalt market is saturated at this time and it appears that in the near future refineries will upgrade bitumens/heavy oils and vacuum residues via technologies such as hydrocracking, H-Oil and LC-Fining to produce more transportation fuels. Therefore, there will be economic pressure for the utilization of the resulting processed residues as road and roofing asphalts rather than low grade fuels. In this work the use of processed residues for the production of roofing asphalts has been investigated. Results show that 28-30 wt% of processed residue can be blended with 150-200 penetration asphalt cement to produce Type I roofing asphalt. The physical properties of the roofing asphalts were examined in terms of the composition (saturates, aromatics, resins, and asphaltenes) as well as average molecular weight of the maltenes and asphaltenes determined by gel permeation chromatography. The results are compared with two roofing asphalts obtained from petroleum refineries.
