OXIDIZED BITUMEN 90/40

Oxidized Bitumen 90/40 is an oxidized Asphalt produced by oxidizing a selected petroleum asphalts without adding the catalyst. Bitumen oxidized 90/40 has high softening point, high flash point and it is highly stable during melting. This kind of Blown Asphalt is mostly using in the Mediterranean and specially morocco market. Blown Asphalt 90/40 is produced by the air-blowing of penetration grade bitumen. This is done at high temperatures, resulting in a material of a much higher penetration index. Oxidized Bitumen is a solid or semi-black solid material and gradually liquid when heated. Oxidized Bitumen grades are blown or oxidized bitumen ‘s which are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumens and a variety of uses in industrial applications. Oxidized Bitumen 90/40 is produced by either Continuous or Staggered Blowing Process. Heated Penetration Grade Bitumen under controlled environment is blown with air which controls the Oil Content in the Bitumen while it oxidized. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges. As said before, Oxidized Bitumen 90/40 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. In addition, the numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value measured by Ring and Ball method as determined by ASTM D36. Also, the penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.

USES OF OXIDIZED BITUMEN 90/40

There are many uses of this grade of oxidized bitumen but it is mainly used for industrial applications such as roof felts, waterproofing, roof and floors anti-rust pipe coating, anti-slip layer compound, sound dampening felts, coats for automobile industry, joint filling compounds, sealants and bituminous mastic. Oxidized bitumen 90/40 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 90/40 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 90/40 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.

HANDLING AND STORAGE OF OXIDIZED BITUMEN 90/40

Heating bitumen for the most final uses is a critical stage. Generally, the most important aspect in this procedure is heat control. Temperature and heat control can affect various characteristics of the product, including its quality. The safe and recommended maximum temperature is 230℃. All oxidized bitumen is risk-free at below 100℃ during shipping operations. Heating and heat transfer should be controlled. Improper heat transfer may cause overheating and release low flash vapors and these unwanted side products have a higher fire risk. Also, melted bitumen should not be left in the boiler to cool down. Because it can cause overheating and requires more positional energy. Furthermore, proper placement and installing of the temperature and pressure monitoring and control devices is very important. Because if their placement is not right, thermometers can’t display the real temperature, which can lead to poor monitoring and thermal conductivity.

PACKING OF BLOWN ASPHALT 90/40

Oxidized Bitumen 90/40 in various packing, including bitumen 90/40 is available in 20 & 50 Kg Kraft Paper Bags 25 Kg Carton box & 150, 180, 200 Kg Steel Drums:

25 KG CARTON BOX

25kg mold packing: It is most expensive packing since there is mold on and with same mold we can ship out. The mold is carton and at destination you can remove the mold easily.

25Kg Polyamide bag: It is heat resistance bag and filling directly in water to cool down fast. It is firstly use not possible to take out the Polyamide from the bitumen and then use.

25kg craft bag: Craft bag is recycle packing and inside is special material to prevent sticking the bitumen to bag. This grade also possible to load on pallet or without pallet for customer.
