Modification of stearate during the manufacture of stearate creates a highly stable and easy-to-apply paving mixture. In terms of particle size, sulfonated diaspore addition technology is also used with gilsonite and bitumen. Special paving procedures are not recommended where gilsonite is added to the paving mix. After modification with solid gilsonite, the permeability of the finished gilsonite is greatly reduced, the viscosity is greatly increased, and the softening point is moderately increased. When hard asphalt is added to asphalt, it modifies the asphalt to reduce its permeability, increase its viscosity, and increase its softening point. For the manufacture of road pavement mixes, hard bitumen improves the stability of the mix, thus reducing the problems of stampede, cracking, and other types of deformation due to heavy traffic and hot weather conditions. Solid bitumen or "natural bitumen" reduces the temperature sensitivity of most bitumen to achieve high-temperature economic performance at low-temperature properties. Gilsonite is very easy to add and can be added directly to paving mixes or hot asphalt mixes. It also causes minimal disruption to contractor operations. 
The cost of gilsonite is a fraction of the cost of most other mods. Solid gilsonite or "natural bitumen" is easily combined with other hot mix components; It forms a stable solution that will not separate during thermal storage, and its use does not require any changes to the pavement design or to the contractor's standard paving practices. Sodium sulfonated bitumen is a shale control additive used to prevent swelling and cavitation caused by aqueous dissolution of oil shale. Sulfonated bitumen is a stop-loss additive used to seal areas where drilling fluid is lost, which prevents complete loss of drilling fluid and prevents loss of drilling fluid into the formation being drilled, thus acting as a rotational loss of drilling fluid from the bottom of the well to the top. Sulfonated asphalt products can be mixed into most water-based slurries and all oil-based and synthetic slurries. Sulfonated asphalt additives come in two different forms: regular and potassium boosted. Potassium sulfonated asphalt additives are specially formulated potassium salts of sulfonated asphalt. In addition to providing the same unique qualities as conventional sulfonated asphalt additives, it also provides water-soluble potassium ions at approximately 400ppm/lb of product transported in the slurry system. This is useful in those areas that require a specific action of potassium to adequately reduce the swelling of the mud caused by water. 
Gilsonite asphalt manufacturing processes
A method for manufacturing of a gilsonite-like bituminous material with 0 to 1 penetration and a softening point of 130*c. to 180 * c. It consists of subjecting a substance selected from a pure layer and vacuum distillation residue obtained in the production of lubricating oil to solvent extraction to obtain a substance with a permeability of 2 to 30, and then blowing the substance with a permeability of 2 to 30. Gas. 30 at temperatures from 200* to 300*c. Gilsonite or "natural asphalt" strengthens the pavement for greater stability, making it more resistant to deformation problems such as rips and shoving, and increases the bearing capacity of the pavement. In addition, laboratory tests and field results show that a higher resistance to deformation can be achieved while the pavement retains most of its original ductility and resistance to crushing at lower temperatures. Other positive benefits include increased resistance to water peeling and aging. 
Gilsonite Shrink Bag Diaspore reduces the temperature sensitivity of most asphalts, enabling economical high temperature performance compared to low temperature properties. Gilsonite is very easy to add and can be added directly to paving mixes or hot asphalt mixes. It also causes minimal disruption to contractor operations. Technical information - The process of mixing gilsonite in bitumen This is a simple program. It is recommended to use an asphalt tank with a propeller with sufficient agitation to form a vortex. Your best bet is a "lightning" blender or another type of electric blender. Explosion-proof motors are preferred if large concentrations of dust are likely to occur. The diaspore should be added slowly in the vortex. Measures should be taken to recycle hot bitumen through the recycling pipeline. The bottom line is that the minimum temperature should be around 170 to 175 degrees Celsius. Any temperature much lower than this value will increase the mixing time. For typical substitution concentrations (5-10%), mixing is sufficient for 2-4 hours after addition is complete. For masterbatch concentrations (>10% diaspore), overnight recycling is preferred. 
If the bitumen cannot be heated above 170°C, you may consider modifying with Selects Other Grade (60/70mesh) or Selects Grade (200 mesh) instead of HMA Modifier Grade (175°C softening point). However, both selects grades require adding a little more diaspore compared to the HMA grades to achieve the same level of asphalt modification. Dry solid bitumen should be slowly poured into the hot bitumen. If it is added too quickly, lumps may form on the surface. If this occurs, some manual agitation may be required to disperse the blocks. If a horizontal cylindrical tank is used, a gilsonite should be added to the hole with a diameter of about 0.5-1.0 m at the top. Again, it should be poured slowly and mixed with a whisk or hand mixer to avoid lumps. Recycling tubes will be necessary to ensure some proper stirring and atomization effect. Gilsonite does not dissolve immediately. Mixing a tank containing 10-15 tons of bitumen and 5% stearate additive takes about 2-4 hours for adding, plus another 2-4 hours for mixing. Of course, higher Diaspore dosage levels will require longer mixing times. 
Unfortunately, during the mixing process, there is no test or checklist to determine if gilsonite mixes well into the asphalt. But if not, you will see balls or big chunks in the asphalt if it is in an open tank. Then, the best way to check whether the solid bitumen is completely mixed with the bitumen is to compare the original and final permeability of bitumen. Gilsonite or "natural bitumen" mixing process - soluble sachets It may be much easier to pre-pack gelsonite in small polyethylene bags with a certain amount of gelsonite, and then throw it over the hot aggregate in batch equipment. The thickness of the side wall of the bag should be approximately 2 mil (0.005 cm). The total temperature should be around 180°C. It is the temperature of polymerization that melts the bag and the anhydrite, not the heat from the asphalt. Therefore, a temperature of 150-165 ° C entering the mixer is acceptable if the aggregate is sufficiently heated. The use of modifiers to improve the performance of asphalt pavement materials is increasing worldwide. These additives range from polymers and fibers to lime. Pavement engineers and pavement contractors are now taking this product seriously and are interested in both high performance and cost efficiency. 
Gilsonite or "natural asphalt" has long been known as an asphalt booster and hardener. New evidence from laboratory and rapidly growing field work demonstrates that Gilsonite offers a unique combination of high performance and economy for high stress coating applications. The main benefit of Gilsonite is that it produces pavement mixes with higher stability than conventional mixes. Gilsonite is a unique natural hydrocarbon rich in asphaltenes and nitrogen compounds, a granular solid that is fully compatible with bitumen. It can be melted into hot asphalt or added when preparing hot mixes. In any case, Gilsonite dissolves readily in bitumen and requires only a slight increase in mixing time to achieve a homogeneous, easy-to-apply hot mix. The increased stability of a reinforced hard asphalt or "natural asphalt" pavement makes it more resistant to deformation problems such as rutting and buckling, and increases the bearing capacity of the pavement. In addition, laboratory testing and field results show that deformation resistance can be improved while the pavement retains most of its original ductility and low temperature cracking resistance. Other positive benefits include increased resistance to water removal and aging. 
Sulfonated gilsonite
Sulfonated bitumen is a proven and widely used drilling fluid additive with many excellent properties. Oil grade is the basic raw material. Brown in brittle lumps or fluidized powder. Its density is 0.98 g/cm3. Each drilling fluid is partially soluble in water and partially soluble in oil. Sulfonated bitumen has effective properties and a wide range of uses in drilling fluid additives, it is soluble in water and slightly soluble in oil, and sulfonated bitumen appears brown and simply dissolves in the composition. It can emulsify water with oil and prevent the swelling of solids. It also helps regulate low stock removal rates and clean holes. Stabilizes the borehole to prevent any collusion. It is a different form of sodium sulfonate inorganic compound. Multifunctional clay conditioner contributes to clay stability. It is used as oil etc. and helps in emulsifying the oil. This chemical is used to manage losses in sedimentary rocks from rising waters. It is a mixture of solid bitumen, blown bitumen, lignite, sodium hydroxide and mixtures of the latter. Sulfonated asphalt is sodium sulfonated asphalt, which is made water-soluble through a unique sulfonation process. It is a versatile all-mud conditioner that stabilizes shale formations, significantly improves lubricity, reduces high pressure high temperature (HTHP) water loss and enhances filter cake properties in oil- and water-based drilling fluids. 
Sulfonated asphalt products can be mixed with most water-based slurries and all oil-based and synthetic slurries. Sulfonated asphalt additives come in two different forms: plain and potassium-enhanced. Sulfonated Asphalt Additives Potassium sulfonate additives are specially formulated potassium salts of sulfonated asphalt. In addition to providing the same unique properties as conventional sulfonated asphalt additives, it provides approximately 400 ppm/lb of water-soluble potassium ions to the product delivered to the slurry system. This is beneficial in those areas where the specific action of potassium is required to sufficiently reduce clay swelling caused by water. For more than 52 years, the unique chemistry of sulfonated asphalt additives has provided outstanding results in all types of drilling fluids. Regarding the grain size, the technology of adding sulfonated asphalt is also used with hard asphalt and bitumen. As sulfonated/reactive materials, this chemistry can be selected from a variety of particle sizes from soluble materials to mixtures, as well as particle sizes such as abrasives. 
A wide range of size options provides ample opportunity to obtain the required particle size for penetration into different fractions. Sulfonated bitumen is a proven and widely used drilling fluid additive with many excellent properties. Oil grade is the basic raw material. Brown in brittle lumps or fluidized powder. Its density is 0.98 g/cm3. It is partially soluble in water and partially soluble in oil for various drilling fluids. The main consumer of sulfonated bitumen is the petroleum industry. Sulfonated bitumen is an integral part of oil or water drilling. As part of the solution, sulfonated asphalt performs several important functions:
- Acts as a shale retarder; strengthens the walls of the well, preventing them from breaking; promotes rapid closure of fractures.
- Reduce water loss under high pressure and temperature conditions.
- Provides better lubrication of the solution; makes the filter cake less viscous.
