According to the quality and type of analysis provided, it is possible to see a specific target community for bitumen, in which exports to Afghanistan and Pakistan sometimes have a dark color and smell. bitumen exporting countries export different types of these products.
Which grade of bitumen is hardest?
Bitumen penetration test is used to determine the relative hardness of blown bitumen and pure bitumen. One of the applications of degree of penetration is in naming pure bitumen and blown bitumen.
Pure bitumen are named only on this basis, but the criterion for naming blown bitumen, in addition to the degree of bitumen penetration, is also the degree of softness of the bitumen. For example, bitumen 40-50, 60-70, 85-100 and… are among the common pure bitumen in road construction.
The two numbers that come with pure bitumen indicate that the degree of bitumen penetration is in this range. Bitumen R85 / 25, R90 / 15, R110 / 10 and… are examples of common blown bitumen in Iran, the first number indicates the degree of penetration of bitumen and the second number indicates the soft point of bitumen.
By definition, the degree of penetration of bitumen is the length (in millimeters) of a standard needle with a certain shape penetrating bitumen at a temperature of 25 degrees Celsius for 5 seconds under a load of 100 grams.
One of the applications of the results of this experiment is that the hotter the climate of the area where the bitumen is to be used, or the higher the traffic and the heavier the load of vehicles, the more penetrating the bitumen should be. And vice versa, the colder the climate of the area, the less penetration bitumen should be used.
Therefore, the harder the bitumen, the lower the degree of penetration and the higher the degree of penetration of the bitumen, the softer the bitumen. Bitumen with a penetration degree of about 80 are used in asphalts such as asphalt concrete and bitumen with a higher degree of penetration in macadam bitumen and cold asphalt.
Main bitumen exporting countries in 2020
Export bitumen can be obtained from the oil company with the most up-to-date price list of this product. Also, through the brokerages of this company in the Iranian market, you can have very special samples at good prices. bitumen price is determined according to its type.
There are many examples of refined bitumen in the Iranian market.
