High-quality BND 40/60 and BND 60/90 asphalts were made from high-wax Kotur-Tepe crudes with additives - heavy catalytic gasoil, hard asphalt from propane deasphalting, and extracts from selective treatment of oil feedstock - were manufactured in pilot conditions. Production of such asphalts by direct oxidation of vacuum resid is not possible. Optimum feedstock compositions are proposed.
