Given that our company continues to operate as one of the largest bitumen suppliers in 2020, the beginning of the modern bitumen industry can be attributed to 1712 AD, when natural bitumen stones were discovered in France. At that time, bituminous materials were simply spread in the form of lumps on the surface of local roads. This technique was quite successful, and in a short time progress was made in the work, in the form of pulverizing and heating the material before use. With the advancement of science and technology, bitumen has a wide variety of applications in various industries and for various uses, including road construction, floor covering, roofing, underground pipes, metal shields, sealing tanks, canals, bridges, sand stabilization, painting, etc.

Bitumen specifications
1. Degree of penetration: Degree of penetration test is used to determine the hardness of bitumen. In this experiment, a standard needle penetrates the bitumen at a temperature of 25 degrees for 5 seconds under the effect of a 100 g load. The amount of penetration is called the degree of penetration in tenths of a millimeter. The lower the degree of penetration, the harder the bitumen.
2. Viscosity: The higher the bitumen mentality, the more solid properties it shows. It is clear that at higher temperatures it is less psychologically slow. This characteristic of bitumen is measured by C-bolt fiorel device or kinematically.
3. Degree of ignition: Degree of ignition is the temperature that if the bitumen reaches that temperature, the gases emitted from it ignite as the flame approaches and a flame is formed on its surface. The maximum temperature at which bitumen can be heated in the workshop is limited to the degree of ignition.
4. Weight loss: Weight loss of bitumen at high temperature is due to evaporation of some of its oils and petroleum compounds. This characteristic is also one of the important properties of bitumen. The weight loss of bitumen in the oven is measured at 163 ° C for 5 hours (approximate asphalt firing conditions).
5. 5. Ductility or angulation: If we draw a sample of bitumen with a cross-sectional area of 1 cm2 at a speed of 5 cm / min, the amount of increase in sample length before the bituminous property of the bitumen is torn.
6. Degree of purity: We know that the solvent of bitumen is carbon tetrachloride and carbon sulfur. Therefore, if we dissolve a sample of bitumen in any of these materials, its impurities remain, and from there we can determine the purity of the bitumen. The degree of purity is: (weight of bitumen sample) ÷ [(weight of impurity) – (weight of bitumen)].
7. Degree of softness: Degree of softness is the temperature at which bitumen changes from solid to liquid when it reaches that temperature. The higher the softness of the bitumen, the less sensitive it is to temperature changes. The degree of softness of ordinary bitumens is about 60 to 70.
In today’s world, different types of environmental pollution are so widespread that it is quite specialized to deal with each of these branches. One way to help and preserve nature is to manage the quality of materials used in construction projects.
One of the approaches of this company in the field of environmental protection has been paying attention to environmental protection for many years, in this regard, the company has tried to develop green space in its factory environment and using standard systems does not have any environmental pollution. , The use of natural gas as well as double-walled tankers has made its efforts to protect the environment.
The use of petroleum solvents, in addition to being flammable, are the most important pollutants in the environment, and the entry of these solvents into the environmental cycle causes harmful and irreparable pollution.
Until recently, environmental degradation and damage were not given much attention and were not considered serious; But the pollution crisis has led to the simultaneous development of environmental protection, otherwise life on Earth will not be possible. The use of petroleum solvents has harmful effects on the environment and human health. For more information about bitumen price per ton visit our site.
Main suppliers of bitumen in 2020
bitumen sellers In line with global policies to protect the environment, have considered the strategy of using green bitumen (emulsion bitumen) instead of soluble bitumen. Emulsion bitumen (green bitumen) that is currently produced in the world are divided into two general categories, anionic and cationic.
