Most of people know oxidized Bitumen 75/35 Also as blown asphalt 75/35, oxidized asphalt 75/35 is Semi Solid grade of pure petroleum bitumen. As other oxidized bitumen grades .This product manufactured by air-blowning through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business.
Oxidized Bitumenor Blown bitumen grades are produced by passing air through the penetration grades. This process gives the bitumen more rubbery properties than its original formula and they are simply harder bitumen. Hard bitumen under controlled temperature conditions is widely used as an anti-slip layer compound in the piling industry, for the manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts and under carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound and many others. Also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for the oil & gas pipeline joints.
Blown Asphalt in various types and grades as I, II, III including low, medium and high softening point with different penetration and hardness. The blown asphalt types including soft grade grade as 75/25 85/25 95/25 90/40 also medium grade blown asphalt 90/10 90/15 and hard grade, including blown asphalt 115/15 110/15 105/5 105/15 105/35 and special ultra blown grades 150/5.
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 make it a very sought after compound in various applications.
