Bitumen is of great importance in our country and in addition to being used in bitumen and sack waterproofing, it also has other uses such as making asphalt procedures in road construction. Therefore, in this article, first the types of bitumen and its properties will be described, then we will examine the insulation of bitumen and sack.

What is difference between bitumen and tar?
Bitumen is a natural product that is soluble in crude oil and is composed of high molecular weight hydrocarbons. Bitumen has a glossy black color and its main feature is its impermeability to water and its adhesion. The adhesion of bitumen is mostly used in road construction so that it takes a thin layer around the stone grains, sticks them together and forms asphalt.
Bitumens are divided into the following two categories according to their sources of production and production:
Natural (mineral) bitumen Natural bitumen is formed by the evaporation of light crude oil oils that have penetrated the earth’s surface from underground oil sources and are exposed to air and sunlight. Natural bitumens are sometimes mined in the form of bituminous rocks. In ancient times, crude oil penetrated limestone or sandstones. Over time, its mineral oils gradually evaporated and bitumen was left in the rock. The bitumen limestone is ground, the powder is pounded in the asphalt surface and used in asphalt concrete. If the bitumen has a small amount of bitumen, they add bitumen to it, but if the amount of bitumen is high, they add stone to it.
Petroleum bitumens (refined)
This bitumen, which constitutes the major part of the world’s bitumen consumption, is obtained by refining crude oil and in the last stage of distillation. Crude oil is heated to 350 ° C, at different temperatures, gasoline, oil, diesel, fuel oil and other oils are extracted, and finally at 350 ° C bitumen, which is the heaviest material in crude oil. , it will be obtained. This bitumen is ready for consumption after refining and modification. But the durability of natural bitumen in asphalt surfaces and sealing coatings is more than petroleum bitumen.
Bitumen has the following properties in addition to two general properties that are impermeable to water and adhesion:
Bitumen resists atmospheric factors such as cold, heat, freezing and so on. Bitumen deforms from hardness to hardness, paste and water due to heat, and when the temperature drops, it goes through the above steps again and hardens. It is resistant to tensile forces and does not tear, and also has the ability to withstand the forces applied to it by the wheels of cars in road construction.
Road asphalt can be patched if it needs to be repaired so that new and old asphalt stick well and work seamlessly. Visit our site for more information on bitumen demand.
Global demand for bitumen in 2020
largest bitumen suppliers of bitumen emulsion in places where it is not possible to heat the bitumen and it should be consumed as a cold liquid with the lowest temperature, especially in road construction, in terms of safety and prevention of accidents such as fire and ignition , It is important. In addition, in our country, about half a million tons of soluble bitumen is consumed annually for various operations, of which about a quarter is kerosene. Therefore, by using bitumen emulsion instead of soluble bitumen, 125,000 tons of kerosene is saved annually. For more information about Global demand for bitumen in 2020, visit our site.
