Oxidized Asphalt (Blown Asphalt)

Oxidized Asphalt (Blown Asphalt)

Oxidized Asphalt is a specially treated form of bitumen that has been exposed to controlled air during a process of oxidation. This treatment alters the physical and chemical properties of the bitumen, resulting in a product with improved softening point, temperature susceptibility, and resistance to water and other environmental factors. Oxidized Asphalt finds extensive use in various industries, particularly in road construction, waterproofing, and industrial applications. In this comprehensive product description, we will delve into the key characteristics, types, uses, and benefits of oxidized Asphalt, highlighting why Peak Universal Business is your go-to supplier for high-quality oxidized Asphalt.

What is Oxidized Asphalt?

Oxidized Asphalt is produced by blowing air through hot bitumen under controlled conditions to induce the process of oxidation. This controlled exposure to air results in the formation of chemical bonds between the bitumen molecules, leading to an increase in the molecular weight and improvement in the physical and chemical properties of the bitumen. The degree of oxidation can be controlled to produce different grades of oxidized Asphalt with varying softening points, penetration values, and rheological properties.

Key Characteristics of Oxidized Asphalt

  1. Improved Softening Point: Oxidized Asphalt exhibits a higher softening point compared to conventional bitumen, making it more resistant to deformation and flow at elevated temperatures.
  2. Reduced Temperature Susceptibility: The oxidation process reduces the temperature susceptibility of bitumen, making it more stable and less prone to temperature-related variations in viscosity and consistency.
  3. Enhanced Water Resistance: Oxidized Asphalt offers improved resistance to water and moisture penetration, making it suitable for waterproofing applications and protecting structures against water damage and corrosion.
  4. Increased Durability: The enhanced physical and chemical properties of Oxidized Asphalt result in increased durability, longevity, and performance of the finished products, such as roads, roofs, and industrial coatings.

Types of Oxidized Asphalt

Oxidized Asphalt is classified into different types based on the degree of oxidation, softening point, and penetration value. Some of the common types of Oxidized Asphalt include:

  1. Oxidized Asphalt 75/25

Oxidized Asphalt 75/25 is produced by blending 75% of bitumen with 25% of air during the oxidation process. It has a moderate softening point and is commonly used in the manufacturing of medium-hard to hard asphalt mixes, such as mastic asphalt, roofing felts, and damp-proof courses.

  1. Oxidized Asphalt 85/25

Oxidized Asphalt 85/25 is produced by blending 85% of bitumen with 15% of air during the oxidation process. It has a higher softening point and is primarily used in the manufacturing of high-quality asphalt mixes, such as road paving, bridge decks, and airport runways.

  1. Oxidized Asphalt 95/25

Oxidized Asphalt 95/25 is produced by blending 95% of bitumen with 5% of air during the oxidation process. It has the highest softening point and is mainly used in the manufacturing of high-performance asphalt mixes, such as racetracks, heavy-duty pavements, and industrial floorings.

Peak Universal Business Also deals in many other types of Oxidized Asphalt Including Oxidized Asphalt 75/35, 75/30, 85/25, 85/30, 85/40, 90/10, 90/15, 90/40 etc.

Benefits of Using Oxidized Asphalt

Oxidized Asphalt offers enhanced performance and durability compared to conventional bitumen, making it an ideal choice for demanding applications that require high resistance to deformation, temperature fluctuations, and environmental factors.

  1. Cost-Effective

Despite its premium quality and improved performance, Oxidized Asphalt is a cost-effective solution for asphalt manufacturers and waterproofing contractors. Its ability to improve the durability and longevity of finished products reduces maintenance costs and extends the service life of roads, roofs, and other structures.

  1. Versatility

Oxidized Asphalt is a versatile material that can be used in a wide range of applications, including road construction, waterproofing, industrial coatings, and adhesives. Its diverse range of grades and properties allows for customized solutions to meet specific performance requirements and project specifications.

Applications of Oxidized Asphalt

Oxidized Asphalt has a wide range of applications across various industries due to its unique properties and versatile nature. Some of the common applications of oxidized Asphalt include:

  1. Road Construction

Oxidized Asphalt is widely used in the construction of roads, highways, and pavements to improve the stability, durability, and performance of asphalt mixes. Its enhanced resistance to deformation, temperature fluctuations, and environmental factors makes it an ideal additive for producing high-quality asphalt mixes that can withstand heavy traffic and harsh weather conditions.

  1. Waterproofing

Oxidized Asphalt is used in the manufacturing of waterproofing membranes, sealants, and coatings to provide effective protection against water infiltration, moisture damage, and corrosion. Its improved water resistance and durability make it a preferred choice for waterproofing basements, roofs, foundations, and other structures exposed to water and moisture.

  1. Industrial Coatings and Adhesives

Oxidized Asphalt is also used in the formulation of industrial coatings, adhesives, and sealants for various applications, including corrosion protection, chemical resistance, and thermal insulation. Its enhanced physical and chemical properties allow for the production of high-quality, long-lasting coatings and adhesives that can withstand extreme temperatures, pressures, and chemical exposures.
