Description
Summary:A comparative analysis of domestic and foreign standards and technical specifications for paving asphalts is reported. A LUKOIL — Nizhegorodnefteorgsintez OAO draft corporate standard (DCS) for viscous paving asphalts which totally agrees with the foreign specifications was developed. Data from a pilot-industrial run on manufacture of commercial BND asphalt that satisfies the requirements of the DCS and is characterized by elevated plasticity and thermal stability are reported. The compositions of the feedstock and commercial asphalt and the process conditions of oxidation of vacuum resid were refined.
