Bitumen 85/100 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the spaying and chip application. The bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its relatively low air blowing and penetration, it is used in areas with cold weather for asphalting and insulation. It is not cracked in low temperatures.
