The use of fossil fuels has long been of interest to humans, and in the meantime bitumen as an oil product has been of particular importance in the oil industry. Bitumen has a wide range of applications in the construction industry and its use dates back to 3800 years before history.
Today, more than 150 types of bitumen with different chemical and physical properties are made and used in various industries. One of the most important of these bitumens is oxidized bitumen, which dates back to the late nineteenth century.

What is natural bitumen?
When deep-earth crude volatiles evaporate over time against atmospheric agents, a black substance called natural bitumen remains. Natural bitumen includes lake bitumen and rock bitumen.
best quality bitumen with 20.94% by volume of oxygen as a good oxidizer was first made in 1894 for the production of oxidized bitumen during an aeration process in industrial ash and because it was prepared by F.X.Brill, its special properties It was registered under the name of Brillite. Research into oxidized bitumen began, and by 1950 more than 200 research papers had been published in the field. As a result of these researches and studies, as well as the widespread use of oxidized bitumen in the manufacture of moisture insulation, this type of bitumen was ranked among the best types of industrial bitumen. Today, there are 38 industrial units producing oxide bitumen in the United States alone, and in Iran, for the first time in 1980, oxide bitumen was produced and used for waterproofing.
Currently, blown bitumen is one of the most widely used roofing materials in the country. These bitumens are the result of aeration process which is a function of various parameters such as feed type, aeration temperature and aeration rate. Knowledge of how these parameters work is a very important factor to achieve bitumen with the desired quality. At present, in our country, due to the poor quality of polymer additives available in the market and the lack of quality polymeric materials, the vast majority of roof coverings are blown bitumen.
Aeration processes in the production of oxidized bitumen is an exothermic process and includes the process of polymerization and dehydrogenation. This production process has improved over the years. With new techniques, the variables of aeration speed, aeration time, reaction temperature and type of catalyst can be controlled and bitumens with different physical and chemical properties can be prepared in three ways: discontinuous process, continuous process and catalytic process.
Oxidized bitumen has high elasticity and on the other hand has a great variety in terms of permeability and softness and tensile point. Because by controlling the reaction variables, oxidized bitumens with the desired physical and chemical properties can be prepared. These bitumens can be widely used in waterproofing industries. Because this type of bitumen has relatively good flexibility and chemical stability and is resistant to changes in climate, temperature and light. Many uses of oxidized bitumen have been reported in scientific sources. Some of its uses are:
Direct use of pure oxidized bitumen without additives in waterproofing, direct use of two types of oxidized bitumen with different softening points and degree of permeability in the manufacture of moisture insulation by first saturating the fibers with bitumen with low softening point and then It is covered with high soft spot bitumen, the use of oxidized bitumen in the preparation of emulsions to cover joints and cracks and to prevent the penetration of moisture, the use of oxidized bitumen in dry cells and the coating of power cables and joints They are a protective coating for tanks, pipes, railroad tracks against corrosion, other uses in the preparation of adhesives, sound insulation, paints.

bitumen suppliers uk To produce this type of bitumen, petroleum solvents such as kerosene are used to convert bitumen to soluble or liquid bitumen so that when using petroleum solvent evaporates and the bitumen remains to create the desired adhesion.
