Gilsonite NATURAL ASPHALT – NATURAL BITUMEN – GILSONITE: Gilsonite is bitumen in nature and is actually a type of dried bitumen called mineral bitumen or natural bitumen. This product is not made from vacuum baton or refinery waste but is found in nature. At a time when crude oil was transported to the earth’s surface over millions of years, it appeared in the form of crystals near the earth’s surface. Gilsonite or Uintahite is a natural hydrocarbon resins with many properties that have shown remarkable efficiency in various applications in various industries such as oil and gas, ink, paint, construction, asphalt, and casting. Since Gilsonite is highly hydrophobic and resistant to acid and base, it is commonly used in the preparation of asphalt and isogum. Distinctive features of Gilsonite materials are their solubility in non-polar solvents such as carbon disulfide and toluene, as well as molten bitumen. This feature of Gilsonite is used in the production of isogum and waterproofing.
A mixture of two raw materials, a vacuum stick and a vacuum slab is aerated in bitumen production reactors under special pressure and temperature between 200 and 300 degrees Celsius to combine the hydrogen atoms in bitumen molecules with air oxygen and create heavier hydrocarbons by polymerization reactions. It has a lower degree of penetration and a softer point than the original pure bitumen.
Road bitumen is classified based on the results of penetration degree and soft spot tests. Classification is based on impact only.
