Bitumen 60/70
Bitumen Penetration Grade 60/70 is a standard paving-grade bitumen widely used in road construction and asphalt pavement production. It offers excellent adhesion and durability, making it suitable for manufacturing hot mix asphalt for bases and wearing courses. This grade of bitumen is commonly used in moderate climate conditions due to its balanced hardness and flexibility.
Bitumen 60/70 exhibits thermoplastic properties, softening at high temperatures and hardening at lower temperatures, which enhances its performance in road construction. It ensures superior resistance to cracking and rutting, improving the longevity of asphalt surfaces.
Bitumen Penetration Grade 60/70 is one of the most standardized refined paving-grade bitumens, widely used in road construction and asphalt production. Due to its high adhesion, durability, and resistance to environmental factors, it is an ideal choice for producing Hot Mix Asphalt (HMA) in base and wearing course layers.
Bitumen 60/70 exhibits thermoplastic properties, softening at high temperatures and hardening at lower temperatures. This characteristic allows it to perform well in moderate climatic conditions, maintaining a balanced hardness and flexibility. Additionally, this bitumen grade provides excellent resistance to cracking and rutting, enhancing the durability and lifespan of asphalt pavements.
Bitumen 60/70 is widely used in various road construction projects, including highways, urban and intercity roads, and even some industrial applications that require bitumen with balanced penetration properties.
60/70 bitumen is a type of soft bitumen with a penetration range between 60 and 70 tenths of a millimeter. This bitumen is derived from various components of crude oil and reaches its final form after refining and purification processes. Its softening point ranges from 49 to 56 degrees Celsius, indicating the temperature at which the bitumen transforms into a fluid and pasty state.
The price of 60/70 bitumen depends on various factors, including the supply and demand, the type of bitumen and its technical specifications, its physical and chemical properties, its applications and intended use, the brand and the manufacturer or extractor, the exchange rate and its fluctuations, and the level of imports and exports.
- Fluctuations in crude oil prices.
- Global and regional demand.
- Transportation and export costs.
The numbers 60/70 represent the penetration grade of the bitumen. This number indicates the depth of penetration of a standard needle into the bitumen at 25°C for 5 seconds. The higher the penetration number, the softer the bitumen, and the lower the number, the harder the bitumen.
60/70 bitumen is typically produced using one of the following methods:
- Air Blowing (Blowing Process): Blowing hot air into the heavy residue of crude oil (VB) in bitumen production units.
- Straight Run: Direct separation from the distillation of crude oil in distillation towers.
- Road construction and asphalt paving: For producing hot asphalt on roads, streets, and highways.
- Insulation: Used in the insulation of buildings (roofs and foundations).
- Bituminous mastic production: For waterproofing concrete structures.
- Pipe coating: Protecting oil and gas transmission pipelines from moisture.
