Also the soluble binder product separated from natural asphalts by extraction is bitumen. To improve the properties of ...
Method of oxidation of bitumen or the like by feeding a supply stream of bitumen or the like and an air stream or another gaseous oxidant to a reactor in a pressurized state which reactor is a so-called rotating apparatus. The contact between the gaseous oxidant and the bitumen or the like is improved in the reactor by generating turbulence by mixing devices of rotor-stator type that generates ...
Oxidized bitumen is produced by using two oxidation reactors, with a nominal production capacity of 40,000 t/year. During the oxidation process, the distilled bitumen is mixed with heavy oils, fed to a reactor and heated to around 210°C; then it is subject to a continuous supply of air.

Keywords Bitumen Oxidation FT-IR ATR Asphalt Recycling 1 Introduction Bitumen is used as the adhesive agent in asphalt concrete (AC). Therefore, roads and highways con-stitute the largest single use of bitumen in the world [1]. Unfortunately, bitumen, a distillation product of crude oil, is a solution of organic molecules [2–4]
It then migrates through the bitumen to the top of the column. The chemical reactions result in bitumen with a different mixture of molecular structures. Catalysts can influence this process. Blown bitumen has more and stronger molecular interactions than the original bitumen and is therefore more cohesive.
The process of emulsification is accomplished by use of an emulsifier and a stabilizer. A colloid mill is generally used for the preparation of an emulsion. Types Of Bitumen Emulsion: Anionic:In which bitumen particles are negatively charged & Cationic:in which the bitumen particles are positively charged. Brief Process Description: 80/100 ...
OXIDATION PLANTS. PRODUCTION PROCESS. Bitumen heating to 265-270 °C; Transferring melted bitumen to blowing towers; Blowing air to bitumen; Cooling melted bitumen with water; Packing. Preheated bitumen or vacuum residue is introduced into the blowing column just below the normal liquid level. Air is blown through the bitumen by means of an air ...
Oxidation is done when the Admixture enters from the top of the tower and the bitumen at the bottom sprayed through the nozzle at an optimal temperature of 270 degree Celsius. Sampling from the tower has to be analyzed to determine the end point of blowing and the required properties of the final product. Waste and Recovery
Jun 13, 2017· During the production and recycling of asphalt concrete, bitumen in contact with inorganic particles is exposed to air at high temperatures. As a result an oxidation of bitumen, also known as aging, occurs. The reaction between bitumen and air at 163 °C was studied insitu with and without the presence of inorganic impurities by means of fourier transform infrared spectroscopy in the ...

With this reactor, it is possible to control all important process parameters. The Biturox® technology proves that the oxidation process can run
The prevalence of high oxides of sulphur upon weathering bituminous sealants is reminiscent of the sulphates obtained by accelerated photo-oxidation of bitumen (Huang et al., 1995), an oxidation process that leads to water-soluble material (Streiter and Snoke, 1936; Oliver and Gibson, 1972). It is thus not surprising that sealant mass loss is ...
Blown asphalt production process. Bitumen is a hydrocarbon product which is received as the distillation bottom product of an oil refining process and has a high boiling point and viscosity and is soluble in trichloroethylene. Also, the soluble binder product separated from natural asphalts by extraction is bitumen.
The primitive oxidation unit is single reactor type, now it is developed to single tower type or multi-tower sequent continuous oxidation process. Feedstock is heated up to 260-280 celsius degree, compressed air is injected and violently mixed with asphalt to make oxidation reaction, The oxidized asphalt produced will be sent to product tanks ...
Oxidised bitumen has a distinctive consistency at room temperature and a rubbery nature which affects how it responds to stress, or imprint. The process of oxidation increases the stiffness and softening point of the bitumen and considerably alters key physical properties.
Oxidation Bitumen • 85/25 • 90/15 • 95/25 • 115/15 • 135/10 • 120/5 • 110/30. High-tech product is obtained by special refining process without any polymer modification. Its property increased dramatically, far better than conventional bitumen while its cost is lower than PMB.
The oxidized bitumen could be packed in plastic bag also craft bag also in drum and possible to deliver hot in bulk tanker. Oxidation of bitumen 85/40 150/5. When the oxidation of bitumen occurs in the presence of catalytic agents , the process is called catalytic oxidation. By the action of catalysts the reaction rate is changed, allowing the ...
The Technix Multistage Bitumen plant process is highly efficient. As a consequence, very high conversion efficiencies are obtained and minimal feedstocks are expected to be lost in the process - less than 0.1% for bitumen modification compared to typically 2% to 5% in traditional blowing columns and less than 1% for distillation column residues ...
