It is possible to create oxidized bitumen 105/15 by passing air through pure bitumen, which is also referred to as penetration bitumen 60/70. This substance is also known as blown asphalt 105/15 or blown bitumen 105/15. These two names refer to the same thing in different guises. The oxidized bitumen 105.15 has a softening point that is much higher than that of conventional bitumen, despite the fact that its penetration grade is noticeably lower than that of conventional bitumen.

The asphaltene within this bitumen has the capability to polymerize when it is subjected to airflow; as a result, the bitumen gains the ability to stretch. This particular variety of bitumen is referred to as rubberized bitumen, and the letter R in its name denotes that it possesses qualities that are analogous to those of rubber. In most cases, rubberized bitumen is the material of choice when it comes to paving streets and other outdoor surfaces. These numbers provide information regarding the depth of penetration as well as the point at which the material starts to become more flexible. For example, if oxidized bitumen R105/15 is given the grading R105/15, this indicates that the bitumen in question has a penetrability grade of 15 and a softening point of 105.

We manufacture the highest quality Oxidized Bitumen 105/15 ( Blown Asphalt 105/15 ) in different types and export them from Iran and the UAE to other countries around the world.

Before the oxidized bitumen 105/15 can be created in the BBU reactor that is housed in the refinery, the penetration bitumen must first be heated to a temperature range from 240 to 270 degrees Celsius by hot air. As a consequence of this, it is of the utmost importance that the temperature within the refinery be kept at a stable level that ranges between 220 and 230 degrees Celsius at all times. Inside of the reactor, the interaction between the hydrogen atoms in the bitumen and the oxygen atoms in the air takes place as a direct result of the heated air that is present in the surrounding area.

The presence of the heated air is what gets the reaction going in the first place. This reaction, which takes place instantaneously, is caused when the bitumen comes into touch with the air in the surrounding environment. Once that point, it begins to produce steam, which, once it has been produced, needs to be withdrawn from the oxidation chamber in order for the reactor to continue functioning as it was designed to after it has been produced. After the steam has been produced, the space must be depressurized and then evacuated before it can be considered safe. This is a factor that leads to the formation of oxidized bitumen in an immediate and direct way.

Oxidized bitumen 105/15 is versatile and can be used for a variety of purposes, some of which include the construction of roads and the installation of hydroelectric plants. In addition to this, it has applications in the roofing sector, the electrical industry, the flooring and mastics industry, and the oil and gas industry.

  • In hydro projects, the material that must be utilized for the canal lining is blown bitumen 105-15. This specific type of bitumen can be useful in a variety of hydro projects, including the building of embankments, dams, and hydraulic structures; the maintenance and protection of dam linings; the stabilization of sand; and more.
  • Roofing: Oxidised bitumen 105/15 is an essential ingredient in the manufacturing of roofing felts, shingle roofs, damp-proof coating compositions, carriage roofing compounds, liquid roof coatings, and plastic cements. The roofing business makes use of all of these materials in a variety of different capacities. In addition to that, it is utilized in the manufacturing process of liquid roof coverings. In addition to this, it is utilized in the manufacturing process of materials that are afterwards employed in the construction of carriage roofs. This particular strategy for preventing water damage to roofs is, in the vast majority of instances, the most effective one that is now available.
  • Flooring: One of the most common applications for blown asphalt 105-15 is its usage in the installation of flooring. Roofs are another typical application of this material. This is because the material is exceptionally durable, and there is very little possibility that it will slip. There is also the possibility of utilizing bitumen mastic that is resistant to both acids and alkalis. In order to prevent corrosion on facility surfaces, this type of mastic can be used as a coating. These types of facilities include, but are not limited to, chemical plants, fertilizer plants, steel factories, and a variety of other types of facilities. To keep metal from corroding, one can choose from a wide variety of preventative measures. If you already have parquet flooring, you may also use this procedure to restore it to its original condition.
  • Bitumen 105/15 is a component used in the production of laminated boards that are marketed to the electrical industry. This product is utilized in a major manner in a wide variety of operations and activities that are connected to the electrical industry. Using this method, one may secure the covers of electrical connection boxes. In addition to its application in the manufacture of lithium-ion batteries and wires, this material is also put to work in the creation of cables.
  • Bitumen oxidized 105/15 is widely used in the oil and gas industry pipelines as an additional layer of protection against rust and corrosion.
  • Roads: Blown bitumen 105/15 can be used to pave existing roads, create new roads, and perform routine maintenance on existing roads. This is all possible with the use of this material. As an additive, it can be incorporated into asphalt, which is subsequently utilized to pave roads, highways, railroad tracks, and parking lots.
