Grade 85/40

Description of blown bitumen 85/40

Blown Bitumen 85/40 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. Blown bitumen 85/40 is based on petroleum bitumen which is made by blowing 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.
jey pasargad Company guaranty the quality of jey pasargad blown bitumen 85/40 with the arrangement of the international inspector to check quality and quantity of the bitumen 85/40 during the loading to the vessel and controlling the production by QC by batch test report before shipping. jey pasargad Company guarantees the quality to meet with ASTM.

Uses of blown bitumen 85/40

Blown bitumen 85/40 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 bitumen 85/40 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 85/40 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Blown bitumen 85/40 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.

Application of blown bitumen 85/40

The blown bitumen 85/40 should be heated double temperature against the softening point to be able to have flow and viscosity. To use bitumen 85/40, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.
