General description of oxidized asphalt 75/35

Oxidized asphalt 75/35 (in another word, blown asphalt 75/35, oxidized bitumen 75/35) 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. asphalt 75/35 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. Gold Bitumen 75/35 has high softening point, high flash point and it is highly stable during melting. This product, utilized in the industrial sector, exhibits predominantly “solid” characteristics at ambient temperatures and provides SUPERIOR adhesive and waterproofing qualities when applied hot and allowed to cool than Oxidized Bitumen.
Gold Bitumen company guaranty the quality of Gold Bitumen Oxidized asphalt 75/35 with the arrangement of the international inspectors to check quality and quantity of the asphalt 75/35 during the loading to the vessel and controlling the production by QC by batch test report before shipping. Gold Bitumen Company guarantees the quality to meet with ASTM

Paint and sound acoustics Bitumen 75/35

Bitumen 75/35 is sound-isolating and shock-resistant paint for car, building, ship and train is prepared with this bitumen grade bitumen and good anticorrosion and adhesion, and not embrittling at low temperature

Uses of blown asphalt 75/35

Oxidized asphalt 75/35 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 asphalt 75/35 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 75/35 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 75/35 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, dustproof and noise proof for automobile undercoating.

Paving by bitumen 75/35

the blown asphalt 75/35 products are for paving, roofing; 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 blown asphalt 75/35 include roofing, pipe coating, portland cement pavement, hydraulic applications, paint manufacturing.

Application of oxidized asphalt 75/35

Oxidized asphalt 75/35 should be heated double temperature against the softening point to be able to have flow and viscosity. To use asphalt 75/35, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.

Storage/handling of oxidized asphalt 75/35

The validity of asphalt 75/35 is 10 years with multi-time heating and cooling, please refer to MSDS.

Packing of oxidized asphalt 75/35

Various pickings are available for customer’s purpose and conveniences. Gold Bitumen is the manufacturer of oxidized asphalt 75/35 in various packing including Kraft bag, meltable plastic bag, drum, and bulk asphalt 75/35 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. Gold Bitumen oxidized asphalt 75/35 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The asphalt grade 75/35 means the softening point is 75°c and penetration is 35 desi millimeter is produced in compliance and conformity with ASTM standard and meets the following specification.

Guaranty/warranty of blown asphalt 75/35

Gold Bitumen guaranty the quality of blown asphalt 75/35 with arrangement of international inspector to check quality and quantity of the bitumen on each shipment during the loading to vessel and controlling the production by qc team via batch test report before shipping. Gold Bitumen guaranty the quality to meet with ASTM/EN 13304:2009.
