Oxidized Bitumen 115/15, also called Blown Asphalt, is produced by blowing hot air through bitumen 60/70 at 230C, resulting in a higher penetration index. It is semi-solid and exhibits excellent stability, high softening and flash points, making it ideal for construction. It provides superior adhesive and waterproofing properties when heated. Produced from vacuum bottom (VB) in a controlled air-blowing process, oxidized bitumen becomes harder, more viscous, and less volatile, suitable for uses like roofing asphalts and various industrial applications.

Blown Asphalt, is commonly used in various industries, including construction, automotive, and roofing. It serves as an anti-slip compound, sealant, and adhesive for applications like roofing felts, soundproofing, and electric cable protection. Itâ??s also utilized in corrosion protection, pipe coating, civil works, and as a base in synthetic turf and paints. Additionally, Bitumen 115/15 is valuable for sealing, insulation, and in the production of rubber, plastics, lacquers, and varnishes due to its stability and versatility.

Bitumen Penetration 50/70 supplied by RAHA OIL is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil.bitumens are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumen has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. If you are more interested in product information or need to place an order contact or inquire our Sales team. The Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Bitumen penetration grade 50-70 is semi hard penetration grade bitumen used as a paving grade bitumen which is suitable for road. It is also used for the production of asphalt pavements . This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen 50/70 is one of the most used bitumen grades and itâ??s a basic material for all other bituminous products.

Bitumen Penetration 80/100 usually used as a paving grade bitumen suitable to be used in producing hot mix asphalt for road construction and production of asphalt pavements. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The 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. Bitumen Penetration 80/100 is a standard Grade of Bitumen ASTM D946M, typically used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties particularly in road and airport constructions and other similar applications. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grades of Bitumen is produced from Vacuum Residue, which is blown by hot air in the Biturox Blowing Unit; The fully automated process runs continuously resulting in a constant and homogeneous finished product quality. Grade Bitumen can be supplied in any grade and are designated by two numbers to indicate the mid-points of their penetration ranges.

Bitumen Penetration 40/50 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 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.
