    Bitumen (from Lat. bitumen - mountain resin) - solid or resinous products, which are a mixture of hydrocarbons and their nitrogenous, oxygenated, sulfurous and metal-containing derivatives. Bitumen are insoluble in water, completely or partially soluble in benzene, chloroform, carbon disulfide and other organic solvents; with a density of 0.95-1.50 g / cm?.

    Natural bitumen is an integral part of fossil fuels. These include natural derivatives of oil formed when the conservation of its deposits as a result of chemical and biochemical oxidation is disturbed, for example, asphalt, kerite, malta, ozokerite, etc. Extraction is carried out mainly by open-pit or mine method (tar sands).

    Artificial (technical) bitumens are residual products of oil refining, coal and shale. Compositionally similar to natural bitumen.

    Natural bitumen

    Natural bitumen (viscous and liquid) can be found both in pure form and in "bituminous" rocks. Bituminous or asphalt rocks are rocks (limestones or sandstones) saturated with natural bitumen. They were formed in the earth's crust as a result of long-term processes of oxidation and polymerization of oil that permeated these sedimentary rocks.

    Viscous natural bitumens are obtained by extracting them from limestone, dolomite or sandstone impregnated with natural bitumen. Bitumen in nature or natural bitumen are valuable fossil fuels. They are part of oil. Natural bitumen can be viscous or liquid.

    How are bitumens formed in nature? The place of origin of bitumen is the earth's crust. It is here that these rocks are formed in the process of oxidation and polymerization. Natural bitumen have found their application in the chemical industry.

    Natural bitumen in a number of indicators of their properties (high adhesion, weather resistance) are superior to petroleum. The use of natural bitumen in construction is limited by the high cost and relatively small volume of their production. Viscous natural bitumen is used mainly in the chemical and paint and varnish industries.

    Asphalt rock processing can produce asphalt powder, asphalt mastic or asphalt concrete for cold paving. Asphalt mastic is a product of combining asphalt powder with natural or petroleum bitumen.

    Artificial (technical) bitumen

    Another type of bitumen is petroleum bitumen. First of all, it is an artificial product of oil refining. The main constituent of petroleum bitumen is formed by a number of substances: asphaltenes, petroleum oils, neutral resins, asphaltogenic acids, carbides and carbenes. How is this type of bitumen obtained in the industry?

    First of all, in several ways. For example, by deep distillation of oil fractions from tar or residual bitumen. In addition, oxidation of tar, cracking residues or extracts from the selective purification of oils and their mixtures (oxidized bitumen) with air oxygen. This type of bitumen is most widely used in road repair. It is used as tar.

    Building bitumen , as you may have guessed, they are used in construction. When carrying out repair work on the roof of buildings, as well as as a reliable material for waterproofing the foundation, basement, and so on. In addition, this type of bitumen is often used in ordinary fields of activity. Road construction bitumen is used in construction and road repair works.

    To solve many problems, both construction and household mastics are used. These are adhesives that give the material greater strength and durability. I would like to highlight a special type of mastics - bituminous rubber mastic. This type of mastic is used in road construction works. The rubber-bitumen mastic contains bitumen, rubber crumb and a plasticizer. Of course, these products have their advantages, such as high elasticity.

    However, there are also disadvantages. They are primarily associated with the high cost of rubber-bitumen mastic. In addition, the elements from which this type of mastic is made is harmful to human health. So it can hardly be called environmentally friendly and harmless.

    The disadvantages of both natural and petroleum bitumen should be attributed to their increased fragility at low temperatures.
