Definition Of Oxidized Bitumen 90/10
Oxidized Bitumen 90/10 (in another word, oxidized Asphalt 90/10, blown bitumen 90/10) 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 asphalt 90/10 is based on petroleum bitumen which is made by oxidized asphalt 60/70 by 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.
Applications Of Oxidized Bitumen 90/10
Oxidized Bitumen 90/10 uses in the chemical, fuel, lacquers, varnishes, paint paper-pulp-board, textile processing, road construction, pavement, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, crack seal and repairmen, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The asphalt 90/10 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 asphalt 90/10 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. asphalt 90/10 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.
Blown Asphalt 90/10 should be heated double temperature against the softening point to be able to have flow and viscosity. To use asphalt 90/10, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.
