To meet the needs of asphalt manufacturers, road builders, and the construction sector, PERSOL supplies bitumen in different grades namely 40-50, 60-70, 85-100, based on softening points and penetration values as well as Natural Bitumen (Gilsonite).

Types of Bitumen

  • Natural Bitumen

This bitumen is extracted from mines, it is also known as Gilsonite. It is used in many industries, including road construction, the paint industry, the polish and insulation of tanks and tubes, and molding.

  • Coal Tar

This type of bitumen is a black or dark-brown residue produced by the heat treatment of coal

  • Petroleum Bitumen
