Description of Oxidized Bitumen 105/15

Oxidized bitumen 105/15 or in another word, blown asphalt 105/15 or oxidized asphalt 105/15 is a 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 bitumen 105/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by a very hot air. The numbers (105 and 15) relate to the midpoint of the material’s softening point and penetration respectively. The softening point value is in 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.

Bitumen Malaysia guarantee the quality of our oxidized bitumen 105/15 with the arrangement of the international inspector to check quality and quantity of the Oxiasphalt 105/15during the loading to the vessel and controlling the production by QC by batch test report before shipping. RABIT Company guarantees the quality to meet with ASTM.

Uses of oxidized bitumen 105/15

Oxidized bitumen 105/15 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 105/15 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 105/15 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Vehicle undercoating material is also based on oxidized bitumen. Bitumen provides excellent waterproof, dustproof and noise proof for automobile undercoating.

Application of oxidized bitumen 105/15

The oxidized bitumen 105/15 should be heated double temperature against the softening point to support have flow and viscosity. To oxidized bitumen 105/15, surfaces must be dry, clean and after loose particles, formwork, curing products, irregularities, slurries, etc.

Storage and handling of oxidized bitumen 105/15

Oxidized bitumen 105/15 has 10 years validity with multi-time heating and cooling. Please refer to MSDS for more information.

Packing of oxidized bitumen 105/15

A few type of packing is available for customer’s purpose and conveniences. Bitumen Malaysia manufactures oxidized bitumen 105/15 and packed different types of packaging including in Kraft bags, meltable plastic bags, drums, and bulk. Oxidized bitumen 105/15 is a penetration-grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. Bitumen Malaysia can supply oxidized bitumen in any grade and are designated by two numbers to show the softening point and penetration ranges. The bitumen grade 105/15 means the softening point is 105 and penetration is 15 desi millimeters. They are produced in compliance and conformity with ASTM standard and meets the following specification.
