Best Quality of Oxidized Bitumen 85/35 Dubai UAE

Description of Blown Asphalt 85/35

Oxidized Bitumen 85/35 is a semi-solid grade petroleum bitumen and also a polycyclic aromatic hydrocarbon. The process of manufacturing involves the blowing of hot air over base bitumen of grade 60/70, and it leads to oxidation. The oxidation makes the bitumen harder, water-resistant, and also more adhesive in nature.

The “85/35” specification refers to: The first number (85) is the softening point, which is the temperature at which the bitumen starts to become soft.

The second number (35) is the penetration grade, given in tenths of a millimeter, and indicates how deeply a standard needle will penetrate the bitumen under certain conditions.

Alternative Names
Oxidized Bitumen 85/35 is also known by several other names, including: Blown Asphalt 85/35 ,Blown Bitumen 85/35 , Oxidizing Bitumen 85/35 ,Oxidized Asphalt 85/35 ,Air Blown Asphalt 85/35 ,Air-Rectified Bitumen 85/35

Applications of Oxidized Bitumen 85/35

This bitumen grade is widely utilized in the production of bitumen coatings, roofing, insulations, and sheets of bitumen membrane. It also finds applications in chemical industries, fuel, paints, varnishes, lacquers, paper-pulp-board, and textile processing. This bitumen grade is used in civil engineering applications of road construction, pavement, sealing and repairing cracks, roofing, and other building works.

Furthermore, Oxidized Bitumen 85/35 is utilized as a building sealant and insulating material, an adhesive, and as a construction material additive. Furthermore, it is applied in dust-binding and coating, and is also employed as an impregnating and insulating agent in rubber and plastic product manufacturing.

Handling and Storage Recommendations

Heating bitumen in packages is a critical process in most applications. Bitumen is typically melted and heated in on-site boilers. There should be proper control of the heating process to maintain product quality as well as ensure health and safety.

230°C is the highest safe temperature at which bitumen may be handled and must not be exceeded. Owing to the low thermal conductivity of bitumen, local overheating can result from improper heating, with subsequent thermal cracking and the evolution of flammable vapors.

To allow adequate heating, bitumen has to be broken up into small pieces before placing it in the boiler, with exposed surface area maximized. Avoid reheating cold bitumen, as this contributes to possible hot spots and vapor pockets. Temperature-measuring equipment should be placed carefully as readings can significantly vary based on where they are located in relation to the heat source.

Health and Safety Precautions

The following should be noted by employees:

Ensure proper ventilation when heating bitumen to avoid inhaling poisonous fumes.

Use protective clothing, including heat-resistant gloves, shoes, long sleeves, and goggles.

Keep bitumen out of fire or sparks and have fire extinguishing equipment handy.
