Natural asphalt 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. It is as bitumen created in the process of crude oil processing. It is native substances of variable color, hardness and volatility, composed principally of the elements carbon and hydrogen and sometimes associated with mineral matter and essentially free of gas. It is largely soluble in carbon disulfide. It is actually semisolid or solid mixture of hydrocarbon and as much as 50% heterocyclic compounds constituted largely of carbon and hydrogen but having substitutes of sulfur, oxygen, nitrogen and trade metal ,specially iron, nickel and vanadium in the carbon network.
The best known source of the product is Kermanshah and Ilam where has found since 1950.The product was first used as material for waterproofing of boats and bowls. Later when the first asphalt pavements were constructed, it was used as he binder for asphalt mixture. It is stiffer than refined bitumen and its softening point is also higher. This special additive is more ecological way of improving asphalt properties than using other additives.
Advantage and application of natural asphalt
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.
Natural asphalt 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.
Optimizes lubrication, especially at higher temperatures.
Inhibits hydration of the clay fraction in shale and claystone.
Reduces wellbore damage, especially vibration induced formation damage resulting from the stick-slip phenomenon.
It is packed in 25Kg or 50LBS multi paper bag on pallet shrinked wrapped or 500Kg/1000Kg super bag.
20 pallets per container. Each pallet of natural asphalt contained 34 bag.In case stuffing jumbo bag we can stuff 20 jumbo bag per container.
