Gilsonite is a pure hydrocarbon with a melting point of between 160 and 220 ° Centigrade, found in Gilsonite mines that are hardened petroleum. Due to its common oil base, it is easily comparable to crude-oil bitumen (refined bitumen). In combination, the molecules of Gilsonite and bitumen are very close to each other and when combined, they form a compound that has the hardness and durability of Gilsonite on the one hand and maintains the flexibility of bitumen.
Gilsonite is found in underground Gilsonite mines as a hard, black material with a glossy surface. Due to the fragility of this material, it is often used as a Gilsonite powder that is dark brown to black. The main material consists of bitumen which is why Gilsonite is also called natural bitumen and miners seek Gilsonite mining. Since its discovery in the 1860s, it has been used mainly in polishing coatings, electrical insulation, and moisture insulation. Today, this material is used in more than 160 products. The first use of this material today is in black paint, printer ink and powder, mud and cement drilling for oil wells, asphalt optimization, sand casting additives, and a range of chemical products.
The high percent of nitrogenous compounds in Gilsonite gives it high adhesion and at the same time increases its oxidation resistance. The lack of sulfur compounds in the material also reduces the quality of the resulting products. Studies show that adding 5 to 15% Gilsonite to bitumen significantly increases the hardness and deformation resistance without significantly affecting viscosity and elasticity.
Gilsonite is available in various degrees and is classified according to its degree of softness. The degree of softness is used as an approximate guide to dissolving the adhesive and solvent behaviors. The chemical difference between the degrees of Gilsonite is negligible, with only minor differences in molecular weight and resin content.
What is Gilsonite used for?
The use of Gilsonite in driveway construction is very economical and reasonable.
High-level tension tests such as indirect tension tests, freezing tensile stress, and expansion and fracture tension prove that Gilsonite significantly increases the properties of bitumen. The results of periodic measurements and comparisons of the status of asphalt surfaces using Gilsonite and monitored by special computer software by the US Federal Highway Administration have shown that asphalt life is increased from 18 to 29 years.
In places such as tolls, airport runways, highway exits, loading terminals, U-turns, installations, intersections, bus stations, bus lanes, loading docks, parking lots, and squares, Gilsonite is used which is resistant to deformation under pressure, and using Gilsonite increases the passing loads at low or static speeds.
Gilsonite makes surfaces more resistant to shear forces in areas such as runways, highways, and racetracks, facing heavy traffic or high speeds.
Gilsonite can also be used on all types of pavement asphalt, such as mastic asphalt, cement asphalt, smooth asphalt, and ordinary bituminous asphalt.
Gilsonite also improves the properties of asphalt at high temperatures by improving component adhesiveness. As a result, the composition shows more hardness at higher temperatures and less phase change. Gilsonite is widely used in recycling asphalts up to 50%.
Advantages of using Gilsonite in asphalt:
1. If you use Gilsonite in asphalt, there is no need for other polymer modifiers to modify the bitumen.
2. Higher stability, less deformation, more water resistance, resistance against low temperatures, are the characteristics of asphalt made with bitumen modified by Gilsonite.
3. Increase load-bearing capacity.
4. The lowest ratio of Gilsonite compared to other modifiers.
5. Reduce the degree of bitumen penetration.
6. Increasing the softening temperature of bitumen.
7. Increase the viscosity of Brookfield bitumen.
Gilsonite uses are in industries as Gilsonite powder that does not mass during storage. Due to the nature of this hydrocarbon, Gilsonite powder dissolves completely in bitumen and forms very close molecular bonds with the bitumen that are inseparable.

Gilsonite uses around the world
Norway – Oslo
Gilsonite was first used in Oslo in 1970 in areas with heavy traffic or areas with high humidity. The use of Gilsonite increased the longevity and stability of the pavement by almost twice as much as expected. Most importantly, Gilsonite did not show any cracks or slips during the hottest hours of the day in a city like Oslo with a cold climate.
England – Wales
In Wales, by adding 25% Gilsonite to the asphalt mix, they increased the resistance of high-traffic roads and prevented them from deforming.
USA – Seattle, Washington
Seattle berth, which has a very high traffic load due to the loading of containers, uses Gilsonite. Gilsonite, on the other hand, increases pavement strength in wet conditions.
USA – New Jersey
In New Jersey, on high-traffic highways (highways with more than 500,000 vehicles a day, 20% of which are trucks), adding 10% Gilsonite powder to bitumen increases the strength and efficiency of the pavement, resulting in a lifespan of more than 5 years. The problem of cracking has also been solved.
Asia Gilsonite is the largest Gilsonite powder exporter, Natural Asphalt, Naural Bitumen, and Gilsonite wholesaler and there are more than 5 mines in its ownership.
Gilsonite asphaltum helps to increase the stability of asphalt and creates a high adhesion between macadam and bitumen. Gilsonite asphaltum prevents the asphalt from cracking and also the plants do not grow in the asphalt. Gilsonite asphaltum reduces the consumption of bitumen. Another advantage of Gilsonite asphaltum is that Gilsonite asphaltum helps asphalt to not loosen or soften in the summer when it is mixed with asphalt due to sun exposure and does not step or collapse. Most airports in the world with the use of Gilsonite become hard asphalt with no deformation in summer and winter.

Most airports in the world with the use of Gilsonite become hard asphalt with no deformation in summer and winter. While hot asphalt mixes have poor flexibility after cooling (such as cement), the Gilsonite retains its flexibility and softness by retaining oils and keeping the asphalt flexible by filling in micron voids. The use of Gilsonite in five-year asphalt indicates a decrease in viscosity of more than 30%, an increase in creating of up to 30%, and an increase in Marshall Resistance of up to 40%. In contrast with many engineers’ ideas, Gilsonite could not provide the required stiffness for the pavement, but the studies show that the resistance to on-site loads is higher than conventional asphalt. The stability of this type of asphalt against grooving and stretching is more and also the bearing load of the pavement is more. In addition to the above benefits, the effect of ultraviolet light, oxidation, and water penetration in the asphalt is also reduced, which has a direct effect on the life of the substructure. Asphalt mixed with high-grade Gilsonite is completely integrated without the need for other balancing materials that are added to the asphalt in powder form. Gilsonite, in the whole or part, or as a supplement in terms of value and price, can replace SBS polymers in asphalt balancers.
Bitumen is a natural hydrocarbon, pure, high asphaltene (70%) and nitrogen compounds (3%) and ‘perfectly compatible with asphalt’. This product mixes easily with hot water. The bitumen powder is used as a modifier and increases temperature resistance, endurance, and tensile strength. Also, the high concentration of asphaltene in bitumen increases the viscosity of the bitumen. Typically, 5 to 15% bitumen is used as viscosities for bitumen. Consumption of bitumen powder greatly increases the life of asphalt and therefore is most used in road construction and the reason for its use is because of its availability. Bitumen is a substance that shows a specific behavior at any temperature. At ambient temperature, it has neither the behavior of an elastic material nor a viscous material. The form of bitumen includes a combination of these two states. Bitumen from petroleum products is often produced in refineries. Bitumen is solid at ambient temperature. As the ambient temperature increases, it becomes a paste. It becomes liquid if we raise the ambient temperature too high.
Water impermeability and bitumen adhesion are the properties that make this material have many applications.
Gilsonite powder for sale
There are two general methods of putting Gilsonite for sale:
- Gilsonite suppliers in powder form
- Gilsonite suppliers in lumps
Gilsonite powder form:
In this method, the customer announces to the Gilsonite supplier company what size powder he needs and in what size and with what analysis he needs Gilsonite. The Gilsonite extracted from the Gilsonite mine is then processed and packaged in the desired size. Small packages of Gilsonite are transferred to larger packages and are ready to be loaded for export. Gilsonite powder can also be used in rail exports. This can also bring more returns to both Gilsonite exporters and Gilsonite customers and buyers.
Gilsonite supply in lumps:
The Gilsonite consuming devices around the world have made it possible to produce and supply the required Gilsonite in lumps. This has fewer steps than the previous method. After leaving the mine, Gilsonite enters special shredders and is produced in larger sizes than the previous method. The prepared Gilsonite is then analyzed according to the customer’s requirements and loaded in special packages. 1-ton jumbo bags are one of the best examples of Gilsonite packaging containers that are also paid a lot of attention in the export sector. This sample of packaging also brings more reasonable prices for customers.
Gilsonite powder, also known as asphaltite or bentonite, is a natural hydrocarbon resin and is the best moisture insulator in nature. Gilsonite powder is dark brown. This product can be used in drilling, oil and gas materials, ink and paint industry, asphalt, and coating. So many companies provide Gilsonite powder for sale. By providing Gilsonite powder, the Gilsonite consumer simply asks for the required mesh and delivers the purchased Gilsonite powder to the desired mesh. On the other hand, different packages can be prepared and used for export based on Gilsonite being supplied in powder form.
Gilsonite Mining Season is usually spring to summer because most of the Gilsonite mines are full of water when it rains and the miner does not take the risk of putting Gilsonite for sale. When oil prices rise, the price of Gilsonite also rises. The number of active Gilsonite mines is usually 10-12 mines per year, but each of them must start putting Gilsonite s for sale, which affects the price depending on its size and the load output of the area.
Gilsonite powder suppliers
Gilsonite is a material that is extracted from the Gilsonite mines and then converted into Gilsonite powder by micronizing devices in Gilsonite Company. Gilsonite powder is mainly used in the industry. By producing micronized mineral bitumen powder or Gilsonite in various types of mesh, it can be easily used in various industries such as paint production.
Gilsonite can be used in the production of various types of insulation for the roof, which prevents the penetration of water and moisture. The special properties of Gilsonite have led to Gilsonite use in the production of insulations.
Production and meshing of Gilsonite micronized powder has been done in mineral smelting factories by Gilsonite manufacturers in many countries and therefore it is possible to buy them at a reasonable price. It is possible to buy and use the micronized powder in different volumes. In this method, the Gilsonite consumer customer simply declares the required mesh and delivers the purchased Gilsonite to the desired mesh. On the other hand, different packages can be prepared and used for export based on Gilsonite being supplied in powder form.
Bitumen powder is used in the production of asphalt, which can be used to asphalt city roads and driveways. Its important advantage is that the thickness of asphalt is reduced during construction.
Gilsonite powder is dry and ground so it is exported in powder form. First, it comes from the Gilsonite mines to the Gilsonite Company in the form of lumps and is tested there.
Asian Gilsonite suppliers export their products to the ports of Seattle and New Jersey (USA), Frankfurt (Germany), Oslo (Norway), Melbourne and Sydney (Australia), and in many Indian cities. The Gilsonite powder is used to increase the life of the asphalt. In this regard, the Gilsonite manufacturers use micronized Gilsonite powder with 200 meshes and solubility of more than 85% in carbon disulfide, the Gilsonite companies have modified asphalt by increasing strength and friction, reducing penetration and cost, and reducing toxicity.
Laboratory results show that the strength of the resulting asphalt in the presence of 10% Gilsonite is 1357 kg, while in the absence of Gilsonite is 1097 kg. Gilsonite-modified asphalt has stronger strength, durability, and life than conventional asphalt. Besides, it is cheaper, greener, and has more bitumen than ordinary asphalt.
Those Countries are customers of Gilsonite exporters that use Gilsonite for asphalt, as well as those that use it for insulation. At present, most Gilsonite exports to India, followed by Australia, Europe to China. France and the United States also have these reserves, but the price is very high compared to Iran. Other countries do not know much about this product. The first country that knew this product well and even guided other countries in discovering these Gilsonite mines was India. Of course, the amount of Gilsonite exports is not high per year and Gilsonite companies do not export more than twenty thousand tons per year. Price is determined by competition, Gilsonite suppliers, and demand and does not have a specific price. The better the quality, the higher the price will be. But it is demanded that sets the price of Gilsonite.
Gilsonite, or North American asphalt, is a natural hydrocarbon found in the Unite area of northeastern Utah. This natural asphalt is as hard as petroleum asphalt and is more commonly known as natural asphalt, unit asphalt, or asphalt.
The Gilsonite Company has a Gilsonite Wholesale network of petrochemical and refinery products throughout Asia, Europe, and Africa, as well as having engineers and experts in the upstream and downstream branches of oil, gas, and petrochemicals as one of the strongest companies in this field.
Gilsonite Lake is the name of a lake near the village of Labro, in the southwest of Trinidad and Tobago, which is known as the largest Gilsonite powder suppliers’ lake in the world, which is why it is also called Trinidad Bitumen. Major Gilsonite companies exist in India, Canada, Colombia, Venezuela, Russia, Australia, and Iraq.
Gilsonite for sale
The simple form of Gilsonite can be easily dissolved in refined bitumen and contained as a high-pressure solution or added directly during the production process. Therefore Gilsonite companies put the Gilsonite for sale as well as the Gilsonite spray rig for sale to take advantage of them in driveways. The use of natural Gilsonite also plays an important role in asphalt recycling. The use of Gilsonite makes it possible to recycle old asphalt and makes recycled asphalt as durable as new asphalt. However, recycling ordinary asphalt does not have the same results as new asphalt, and the pavement made in this case is vulnerable to cracking.
The Gilsonite companies also produce Gilsonite spray rig for sale because of the unique properties of Gilsonite, including high strength and fatigue resistance, reduced temperature sensitivity, high resistance to deformation, increased hydration resistance, reduced pavement thickness, and environmental compatibility, make the use of this material economical in road construction. Gilsonite can be added directly to the asphalt.
For the use of Gilsonite in asphalt, the amount of ash in it does not matter. The presence of ash in Gilsonite is not an unpleasant factor and it is even used to improve asphalt by mixing it with other additives. Some experiments show that the presence of sulfur compounds in Gilsonite during asphalt concreting makes asphalt more resistant, so the presence of sulfur in Gilsonite is an important and good factor for mixing it with asphalt. As a result, it is very suitable for mixing with Gilsonite asphalt.
