Oxidized Bitumen (Blown Asphalt) is a form of bitumen that has undergone oxidation, resulting in a material that is harder and more viscous. This procedure includes exposing bitumen to high-temperature air, which causes it to shed some of its volatile components and become more resistant to temperature fluctuations.
For roofing and waterproofing applications, oxidized bitumen is often utilized in the building sector. It has good adhesive qualities and is resistant to water, heat, and UV radiation. This makes it perfect for high-stress applications including bridge decks, airport runways, and parking garages. Oxidized bitumen is a crucial component in many building projects because to its increased durability and performance.

In the bitumen oxidized production plant, the production process is as follows:

  1. Heating the bitumen at a temperature between 230 and 270 degrees Celsius.
  2. Moving the molten bitumen to the blowing towers.
  3. Aerating the bitumen with air.
  4. Bringing the molten bitumen down to temperature using water.
  5. Packing.


Continuous or staggered blowing processes are used to create Oxidized Bitumen, blown asphalt, and blown bitumen. Air is blown over heated penetration grade bitumen in a controlled setting to regulate the oil content of the bitumen as it oxidizes. The middle points of the softening point and penetration ranges for each grade made for a certain application are shown by two numbers.

The oxidation process is an outline of the steps:

  1. A technique involving continuous blowing.
  2. A method of blowing that is not continuous.

Catalysis and anti-catalysis are two more processes that are involved in the completion of these two operations. The act of introducing a chemical material throughout the process in order to minimize the amount of time needed for the blowing reaction is known as catalysis.

Because of the following advantages:

  • Ease and simplicity in adjusting blowing conditions and, as a consequence, having output of varied grades
  • Ease in creating the unit
  • Simplicity in both the technology and the financial investment required.

The technique of creating in a discontinuous manner is selected.

The following is a rundown of the technical aspects and operational conditions:

It is recommended that the blowing be performed from the bottom of the blowing tanker. The reaction that takes place when bitumen and air mix produce heat. If the amount of heat generated by the combination is significant, the amount of heat generated by the reaction can be regulated by injecting water.

Both the amount of air that is mixed in and the total volume of air that is blown are crucial variables in the blowing process. In this situation, in order to make bitumen, either 90/15 or 85/25 distilled used oil or crude oil should be introduced into the product according to the amount 20-25%. If this is not done, the fragility of the bitumen will result in poorer output.

The rate of the manufacturing process reaction may be increased by increasing the heating temperature, the quantity of air injection, the length of time, and the tower pressure. The optimal temperature range for production operations is between 265-270 degrees Celsius, and this range should not be exceeded under any circumstances. This is because at higher temperatures, specifically 288 degrees Celsius, the intensity of the reaction becomes more severe and uncontrollable, which can cause an explosion in the tower. It is not beneficial to the system for bitumen to remain in the tower for an extended period of time under any circumstances; once it is ready, it should be transferred to a drum or an empty tanker.

If the liquid surface in the blowing tower is low, then only up to a certain limit should be introduced to the system. This is because any further air that is added will accumulate in the empty areas and very certainly cause ignite. And if the temperature is maintained at a high level, the internal heat of the tower will cause fats to climb, which will lead to an issue that causes an explosion inside the system.

The blowing tower has been filled up to 70 percent capacity. Air infusion takes place at temperatures ranging from 190 to 232 degrees Celsius. Sampling and testing of the characteristics of the bitumen are used to determine the ultimate point of blowing. In conclusion, in order to have the capacity to load and pack the goods, the temperature of the product should be maintained between 150 and 165 degrees Celsius.

oxidized bitumen production process or blown bitumen production process


Oxidized bitumen is a specially treated asphalt binder. It is produced by controlled air blowing of bitumen at elevated temperatures. While the exact composition of oxidized bitumen may vary depending on the manufacturing process and specifications, the main components and materials involved in its production include:

  1. Bitumen: Bitumen is the primary component of oxidized bitumen. It is a highly viscous, black, or dark brown petroleum residue obtained from the distillation of crude oil. Bitumen is a complex mixture of hydrocarbons and contains predominantly high molecular weight compounds.
  2. Air/Oxygen: During the production of oxidized bitumen, air or oxygen is introduced into the bitumen at elevated temperatures. The controlled oxidation process causes chemical changes in the bitumen’s molecular structure, resulting in the desired properties of oxidized bitumen, such as increased softening point and improved resistance to aging.
  3. Heat Source: The oxidation process requires a heat source to raise the temperature of the bitumen. Various heat sources can be used, such as direct flame, hot air, or steam, depending on the specific manufacturing setup.
  4. Catalysts: In some cases, catalysts may be added to accelerate the oxidation process and modify the properties of the bitumen. These catalysts can include metallic compounds or additives specifically designed for the oxidation process.
  5. Additives/Modifiers: Depending on the desired performance characteristics, additives or modifiers may be incorporated into the oxidized bitumen. These additives can include polymers, rubber, or other materials that enhance properties such as elasticity, durability, or resistance to aging.
  6. Fillers: In certain applications, fillers may be added to the oxidized bitumen to improve its properties or modify its consistency. Common fillers used in bitumen products include mineral fillers such as limestone, sand, or hydrated lime.

It’s important to note that the specific formulation and composition of oxidized bitumen can vary depending on the intended application and specific requirements. Manufacturers may have proprietary formulations or may tailor the composition based on customer specifications.


Bitumen Oxidized Specification, often known as Blown Bitumen, is created by injecting hot air into the bitumen that has been penetrating. Because of this activity, the bitumen will be rubberier than its initial formulation, and it will also grow tougher. This bitumen recovers the weight that was lost during the heating process. Because of the low thermal sensitivity, the softening point is much higher than regular bitumen, and the penetration index (PI) is higher than road construction bitumen (8>PI>2). This is because the letter has a gel-like structure due to the accumulation of asphalt. The reason for this is that the softening point is much higher than regular bitumen. The building industry makes use of a wide variety of diverse applications that call for certain physical features that this grade has.

When penetration-grade bitumen is subjected to air-blowing, the resulting product is referred to as blown bitumen. This is carried out at high temperatures, which results in the production of a substance with a much greater penetration index. The primary component of blown bitumen is petroleum bitumen, which is produced by blowing bitumen 60/70 with extremely hot air. Blown bitumen is also known as blown asphalt. The label “blown bitumen” alludes to the point in the softening point acceptance criterion that is located precisely in the middle. In addition, the numbers correspond to the point in the material’s softening point and penetration that is precisely in the middle of their respective ranges. The value for the softening point that was established using the Ring and Ball technique according to ASTM D36. Additionally, the penetration value is 1/10 millimeter, as established by either IP49 or ASTM-D5.


Oxidized Bitumen properties are:

  • Reduced temperature susceptibility
  • Exhibits a more ‘solid’ character at ambient temperatures
  • A high index of penetration
