A method is proposed for producing viscous bitumen for road use with improved physicomechanical properties by modifying BNA 130/200 bitumen obtained by oxidizing tar from the coking of Shubarkol coal at 160°C using elemental sulfur, with an air supply of 1.5 L/min for 1.5 h. The resulting BNA 60/90 bitumen has a total tar content of 52.09 wt %, with 21.99 wt % hydrocarbons, 24.99 wt % asphaltenes, and 0.93 wt % carbene and carboid. In terms of its penetration index, the viscous BNA 60/90 bitumen belongs to group II on the basis of its rheological properties and deformational properties. That corresponds to sol–gel structure.
