Abstract:
     A process for preparing high-viscosity asphalt used for highway is prepared from the propane deasphalting asphalt extracted from Oman's crude oil through semi-oxidizing, and features high viscosity of 600-1000 Pa.s at 60 deg.C and high resistanc to high-temp deformation and low-temp cracking.
