Oxidized Bitumen 95/25 Definition
Oxidized Bitumen 95/25 is Semi Solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business. Oxidized bitumen95/25 is based on petroleum bitumen which is made by oxidized bitumen 60/70 by very hot air. The numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value is the degrees Centigrade measured by the Ring and Ball method as determined by ASTM D36. The penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.
oxidized Bitumen is industrial bitumen which is dark, petroleum residue modified by the oxidation process. Oxidized Bitumen is produced by passing air through bitumen under controlled temperature conditions. Its consistency ranges from highly viscous to solid. Blown bitumen grade has technical advantages such as durability, flexibility, water resistant and chemical stability. There is the different grade of blown bitumen.
Oxidized Bitumen 95/25 Applications
Oxidized bitumen 95/25 uses in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement ,crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The oxidized bitumen 95/25 products are for paving. also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf; typical uses for bitumen 95/25 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. bitumen 95/25 is using insulation and isolation bitumen membrane sheet. Also, Car undercoating Automobile industry is specially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dust proof and noise proof for automobile undercoating.
Oxidized bitumen 95/25 should be heated double temperature against the softening point to be able to have flow and viscosity. To use bitumen 95/25, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.
