Oxidized Bitumen VS Penetration Bitumen

Oxidized Bitumen VS Penetration bitumen evaluate in some features as: Penetration Bitumen is a viscous, black substance that either occurs naturally or is derived from crude oil. Penetration Bitumen is commonly used in road construction, waterproofing, and various other applications. On the other hand, oxidized bitumen is a modified form of bitumen that is obtained by subjecting it to a controlled air blowing process. During the oxidation process, air at high temperatures is blown into the blown bitumen, which causes chemical reactions and introduces oxygen into the molecular structure of the bitumen.

This leads to partial oxidation of the bitumen and changes in its physical and chemical properties. But is there a difference between regular bitumen and oxidized bitumen, Let’s look at some of the key differences between Oxidized Bitumen VS Penetration bitumen

Consistency

Penetration Bitumen is naturally stiff and very viscous, while blown bitumen is harder and less viscous. The oxidation process increases the molecular weight and crosslinking of the bitumen, which results in a more solid consistency.

Softening Point

Penetration Bitumen has a specific softening point, which is the temperature at which the bitumen becomes soft and pliable. Oxidized or blown bitumen has a higher softening point; this characteristic makes this type of bitumen more suitable for applications where higher temperatures or heavier traffic loads are expected.

Durability

Oxidized bitumen is more durable and resistant to temperature changes, ultraviolet radiation, and the effects of aging due to its higher molecular weight and increased cross linking. Blown bitumen also exhibits improved stability and better resistance to deformation and cracking.

Oxidized bitumen VS Penetration bitumen Applications

Bitumen is commonly used in road construction, road surfacing, waterproofing and asphalt production. Blown bitumen is commonly used in specialized applications where greater hardness and resistance to temperature-related deformation are required. These applications are typically in roofing materials, pipe coatings, electrical insulation and joint fillers.

Availability

Penetration Bitumen is readily available as a natural resource and can be obtained from crude oil refining or from natural bitumen deposits. Oxidized bitumen, on the other hand, is produced through a special manufacturing process involving controlled air blowing, which modifies the bitumen. Blown bitumen is usually produced in specialized refineries or blown bitumen production line facilities.
