Bitumen is used in road construction due to various properties and advantages. The bitumen as a raw material in flexible road construction and bitumen as a mix (composing other materials i.e. aggregates etc.) serves certain advantages, that prompt to use bitumen widely in road construction.
An overall bitumen mix is used in the construction of flexible pavement to serve the following needs
Blown Bitumen 75/25 or Oxidized Bitumen or Blown Asphalt is produced by blowing hot air into the penetration bitumen. This action makes the bitumen more rubbery than its original formula and it becomes harder bitumen. This bitumen recovery the weight loss under heating. Due to 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) due to the letter has a gel-like structure because of asphalt accumulation. Blown Bitumen 75-25 is Semi Solid grade of pure petroleum bitumen. Special physical properties of its grade can be used in different applications in the construction business.
Blown Bitumen 75/25 is produced by the air-blowing of penetration grade bitumen. This is done at high temperatures, resulting in a material of a much higher penetration index. RAHA Bitumen 75/25 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The designation of the Blown Bitumen 75/25 refers to the midpoint of the softening point acceptance criteria.
Our Bitumen partner Co. is also capable of producing other grades of Oxidized Bitumen according to the specifications of individual clients. Some of the major advantages of Oxidized Bitumen are that it is completely water resistant, highly flexible and durable. Further, it is chemically very stable. Oxidized bitumen is a very flexible compound that is not only chemically stable but also a very durable compound apart from being completely water resistant. Lastly, Oxidized Bitumen has some very prominent technical advantages that makes it a very sought after compound in various applications.
Uses of Blown Bitumen 75/25
Blown Bitumen 75/25 is a solid or semi-black solid material and gradually liquid when heated. Oxidized Bitumen grades are blown or oxidized Asphalt â??s which are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumens and a variety of uses in industrial applications.
- Grade 40-50: Suitable for road construction and repair.
- Grade 60-70: Ideal for general paving applications.
- Grade 85-100: Used in various industrial applications.
Hi Sir/Miss
I am Taufiqul Hakim Tsabit as a mandate from End Seller.
We can supply Russian Bitumen of All Specifications to you.
Monthly quantity: 50,000MT - 300,000MT.
Although the usage of Bitumen refers to the ancient time and millenniums before BC for excellent adhesive and waterproofing, still, it has a significant impact in modern lives, construction, surfacing airfield runways, taxi tracks, waterproofing, rolling roads and highways. Today the world's demand for Bitumen accounts for more than 100 million tons per year, which is approximately 700 million barrels of Bitumen consumed annually.
Applying experience gained in the industry, our highly qualified staff are backing Arij's mission to provide their customers with goods manufactured to the highest standards of Bitumen.
We have established long-lasting and close partnerships with manufacturers and refiners from the gulf regions which brings us valuable complements of supplying all types and grades of Bitumen such as Penetration Grade Bitumen (Asphalt), Viscosity Grade (VG) Bitumen, Performance Grade (PG) Bitumen as well as other special types such as Polymer Modified Bitumen (PMB), Bitumen Emulsion (Asphalt), Oxidized Bitumen (Blown Asphalt) and Cutback Bitumen, in any kinds of packages based on customers' requirements

Very high quality of Bitumen in all grades from worldwide well known manufacturers with the best competitive price and delivery terms for those buyers who are looking for short & long term contracts,
Bitumen grade 70/60 is a grade of standard penetrating bitumen and is one of the most widely used bitumen types in the world. This type of bitumen is used as a material for paving roads. This exported bitumen is known as medium-grade bitumen for road construction and asphalt pavement production with superior properties and is used for construction projects.
This grade of bitumen is mainly used in making hot asphalt as a mixture of bitumen and stone materials. The degree of bitumen 70/60 is determined by the penetration test and softening in a certain period of time. As you have noticed, the penetration degree is determined by the penetration test. Only performance parameters such as adhesion, rheology, durability and tolerance of a certain temperature can determine bitumen grading.

We can source excellent quality of bitumen with different grades like 10/20 , 60/70 , 80/100 in both bulk and drums from Oman. Bitumen typically used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties In bulk we can able to offer 50,000 mt per month.
Bitumen Penetration Grade 80/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen supplied by ASI GLOBAL TRADE is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by ASI GLOBAL TRADE is produced from vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.
