Description of Oxidized Bitumen 90/10
Oxidized bitumen 90/10 is semi solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Oxidized bitumen 90/10 is based on petroleum bitumen which is made by blowing grade 60/70 bitumen by hot air. The numbers 90/10 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. Although grade 90/10 is a very good grade, we find that our clients prefer oxidized bitumen 115/15 over other grades. This is mainly to the fact that this grade is one of the most versatile grade of oxidized bitumen in the marketBitumen binder
This is due to many factors, one of which is the poor low-temperature properties of bitumen used as a binder in construction. On the other hand, insufficient resources of raw materials for road production due to the deepening of oil refining processes pose the task of increasing the amount of production of construction bitumen due to modifying additives.Modified bitumen 90/10
For this purpose, it is possible to use less valuable by-products or waste products of oil refining and petrochemical industries as additives, which is economically feasible. The main purpose of modification is to obtain bitumen 90/10 or materials based on them, which allow to expand the range of plasticity of bitumen, strengthen, increase resistance to aging, provide colloidal and mechanical strength, expand the operating temperature range, ensure environmental safety of obtaining and using modified bitumen. It should be noted that the good compatibility of bitumen with various organic substances and polymers, which are able to give bitumen specific improved properties, speaks in favor of modification. Bitumen 90/10 is a stable dispersed system.Properties in construction
It is possible to regulate the properties of bitumen by changing its dispersed structure with additives. As a result of selecting the best bitumen – additive ratio, it is possible to achieve, if necessary, improvement of one or more properties of the finished bitumen material. Modern composite building materials are complex systems, the properties and performance characteristics of which depend both on the properties of the raw materials used separately (fillers, fillers, binders, etc.), and on the nature of their combination, i.e. the characteristics of the contact zone between the components.Uses of oxidized bitumen 90/10
Oxidized bitumen 90/10 is used in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seals and repairs, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, and also to manufacture rubber and plastic products. Oxidized bitumen 90/10 products are 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 oxidized bitumen 90/10 are for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. This grade of bitumen can be used for insulation and isolation in bitumen membrane sheets. It is also used in the automobile industry for car undercoating as it is proven to be an excellent water-proofing, dust proofing and also noise proofing material.Properties in construction

The oxidized bitumen 90/10 should be heated double temperature against the softening point to support have flow and viscosity. To use oxidized bitumen 90/15, surfaces must be dry, clean and after loose particles, formwork, curing products, irregularities, slurries, etc.Storage and handling of oxidized bitumen 90/10
Oxidized bitumen 90/10 has 10 years validity with multi-time heating and cooling. Please refer to MSDS for more information.Packing of oxidized bitumen 90/10
A few type of packing is available for customer’s purpose and conveniences. Gold Bitumen manufactures oxidized bitumen 90/10 and packed different types of packaging including in Kraft bags, meltable plastic bags, drums, and bulk. Oxidized bitumen 90/10 is a penetration-grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. Gold Bitumen can supply oxidized bitumen in any grade and are designated by two numbers to show the softening point and penetration ranges. The bitumen grade 90/10 means the softening point is 90 °C and penetration is 10 desi millimeters. They are produced in compliance and conformity with ASTM standard and meets the following specification.Guaranty/warranty of blown bitumen 90/10
Gold Bitumen guaranty the quality of blown bitumen 90/10 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.Analysis of bitumen 90/10
