In the recent years, Iran has become a major exporter of Gilsonite (Natura Asphalt) to India, China and many other countries in the region. Iran, posses some of the richest mines of Gilsonite, which are used in many industries, including road construction, the paint industry, polish and insulation of tanks and tubes and molding. Gilsonite or Natural Bitumen is also known as Natural Asphalt, Asphalting, and is soluble in petroleum asphalt solvents. Gilsonite is used in the hardening of oil products and it is easily converted to powder form. Gilsonite Natural Asphalt, Natural Bitumen, Hard Asphalt or Hard Asphaltum is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers. Gilsonite can partially or totally replace, or complement, the use of SBS polymers in modified asphalts at a fraction of the cost. Gilsonite-modified asphalts have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping than non-modified asphalts. Gilsonite is also used to make both solvent-based and emulsion pavement sealers with superior appearance and weathering properties. Iranian Gilsonite is the other brand for the mineral known as natural bitumen which is found in Kermanshah and Gilane Gharb located in Iran and also found in Utah in the United States, but can be obtained from Iran at a fraction of the price than that of the U.S.Gilsonite primarily is used in dark-colored printing inks and paints, oil well drilling mud and cement, asphalt modifiers, foundry sands additives and a wide range of chemical products.
