BITUMEN GRADES 40/50, 60/70 & 80/100

الوصف

Mixture of tarlike hydrocarbons derived from petroleum. Black or brown, it varies from viscous to solid; the solid form is usually called asphalt. Bitumen occurs in nearly every part of the world and in nearly the whole range of geologic strata. The term may also refer to synthetic hydrocarbon compounds
Any of various flammable mixtures of hydrocarbons and other substances, occurring naturally or obtained by distillation from coal or petroleum, that are a component of asphalt and tar and are used for surfacing roads and for waterproofing.
Bitumen is a black, oily, viscous material that is a naturally-occurring organic byproduct of decomposed organic materials. Also known as asphalt or tar, bitumen was mixed with other materials throughout prehistory and throughout the world for use as a sealant, adhesive, building mortar, incense, and decorative application on pots, buildings, or human skin. The material was also useful in waterproofing canoes and other water transport. It is also flammable

Bitumen is the heaviest, thickest form of PETROLEUM. Bitumen does not flow freely: it is heavier than water and more viscous than molasses. Most of the hydrocarbons in bitumen are heavier than pentane, and about half are very heavy molecules with a boiling point over 525° C. The light fractions are high in naphthenes (used in making gasoline and PETROCHEMICALS); the heavy fractions are high in asphaltenes (used in making asphalt). Bitumen also contains up to 5% sulphur by weight, and small amounts of oxygen, heavy metals and other contaminants.
 
Most deposits contain mixtures of bitumen, sand, water, small amounts of heavy metals and other contaminants. In its natural state, bitumen is suitable only for paving roads. Compared to conventional crude oil, bitumen contains too much carbon and too little hydrogen
