Oxidized bitumen

90/40, 75/25, 85/25, 90/15, 105/35, 150/5, 95/25

Oxidized bitumen is Blown Asphalt which is exporting in various grades as Oxidized Bitumen 115/15, Blown Bitumen 90/40, 75/25, 85/25, 90/15, 105/35, 150/5, 95/25 and any other grade will produce according to order.

Oxidized bitumen (also known as blown bitumen) is manufactured by blowing air through bitumen. To be more specific, in the air blowing method of bitumen production, the air in 190 to 200 c is blown to the substance and the oxidized or air blown asphalt is produced. Due to the air blowing process, oxidized bitumen comes with rubberier properties. Among unique specifications of blown bitumen are flexibility, increased durability, and resistance to water.

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.

Blown bitumen grades broadly used as an anti-slip layer compound in the industry. It is also applicable to roofing and waterproofing industries, piling industry, sound dampening, the automotive industry, and so on. As oxidized bitumen is hard, its softening point is much higher than regular bitumen. Also, its Penetration Index is higher than a regular one.



The founders in the year 2012 have established the Kiapetro company with the aim of better providing and making use of Bitumen and Petroleum Products.
