Natural Asphalt Powder for Asphalt And Drilling Additive

General Description of Natural Asphalt in Drilling Mud

Natural asphalt Powder in Drilling Mud and other asphaltic type materials penetrate shale pore spaces as a drill bit penetrates a formation. It is assumed that a plastic-flow mechanism will allow the asphaltite to extend into the pores of the shale, thus, reducing fluid loss or mud invasion with a tendency to bond the shale and prevent sloughing.

Natural asphalt Powder is derived from the natural mutation of petroleum. This mutation happened a million years again under the influence of bacteria. This bacterial decomposition of petroleum resulted in reduce content of saturated hydrocarbons, mainly n-alkalenes and light oil which became heavier and more viscous , taking the form of asphalt. It is natural product a bituminous limestone in which carbonate of lime and pure natural asphalt are most intimately combined by natural agency.

Natural Asphalt are natural occurring hydrocarbon substances characterized by a high softening point (above 110° C) in the class known as asphaltite.
They are mined much like other minerals and sold essentially in their native state. They are fully compatible with asphalt and have long been known as asphalt hardeners and reinforcing agents. Natural Asphalt is currently sold all over the world as a road bitumen modifier in the form of a dry bulk solid granular powder.

Natural asphalt together with a continue layer or in three ply with two layer of a water proof and permanently natural asphalt cement. It is surface coated after it is laid on the roof with very durable liquid asphalt. The best advantage is saturating and cementing together with felt and surface. Application of the material and petroleum seepages goes back to ancient times, when people in southwest of Turkey used these for fuel and medication purpose. In ancient Egypt these material were also used in mummifications. It is a product of crude oil and forms as it migrates toward the ground surface, this material is using as industrial material now.

The produced powder is directly used in warm road bitumen, reducing the bitumen by 10-20. The micronized Natural Asphalt powder is used as a modifier in hot asphalt to add to its functionality, rigidity, stability and lifetime. Also, Natural Asphalt decreases penetration rate and increases viscosity, softening point, thermal resistance, resistance to deformation and resistance to water stripping. Also, this powder, due to having nitrogen-containing heterocyclic materials, adds friction between the road and the cars’ wheels, that, in turn, will increase the quality of driving in the rain and while braking.

Natural Asphalt has two types of molecules, a straight carbon, and a ringed carbon. When you heat the Natural Asphalt Powder, the two components separate. The ringed carbon vaporizes and is called a volatile. A straight carbon remains and becomes the residue, or sometimes called carbon or carbon black.We are exporting the carbon in the residue form. The volatile after cooling done can be used as a fuel and fuel should be refined to segregate sulfur or other elements and add additives.

Natural Asphalt is the naturally-occurring mixture of bitumen and mineral matter formed by oil seepages in the earth’s crust. Iran Natural Asphalt Powder in rock form is available in the west of Iran between Ilam and Kermanshah and Iraq border.

Application of Natural Asphalt Powder in Drilling Additive

Application of Natural Asphalt in heavy traffic area like junction or bus station Natural Asphalt Powder using as the additive in paving on the special location of roads like the bus station or signal points and junction. Due curing of pavement because of cold or high temperature, the weight of trucks and cars, sun, rain, snow road construction companies are looking for new technology and material to use to improve crack and deformation and all above problem.

Benefits of Natural Asphalt Powder in Asphalt

• It is an environmentally friendly natural additive
• It is affordable and leaves a great saving on materials
• High strength and fatigue resistance
• Reduced temperature susceptibility
• Reduced pavement thickness

Advantage of Natural Asphalt Powder in Asphalt

• Natural Asphalt Powder is added to asphalt pavingmixes to improve pavement performance. In the case of doing this project, the lifetime of asphalt in Iran will be doubled and tripled.
• With this method, the price of asphalt will be decreased by around 10%.
• Decrease in bitumen’s penetration rate and increase in resistance to water stripping.
• Improves ductility and resistance to low-temperature cracking. Increase in bitumen’s softening point temperature.
• Increases the durability of the pavement.

Packing of Natural Asphalt

Natural Asphalt is packed in 25Kg or 50 LBS multi paper bag on pallet shrink wrapped or 500Kg/1000Kg super bag.
