Buy The Latest Types of Gilsonite asphalt At a Reasonable Price
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
