PENETRATION GRADE BITUMEN
EN Standard – Bitumen 50/70
Bitumen 50/70 is a medium-hardness grade of bitumen with a penetration range of 50 to 70 tenths of a millimeter. This grade is designed to offer a balance between hardness and flexibility, making it suitable for a wide range of climatic conditions and traffic loads. Bitumen 50/70 is known for its versatility, providing reliable performance in both hot and cold environments. Its intermediate viscosity allows it to perform well in areas with moderate temperature variations and diverse traffic conditions.
Produced through the distillation of crude oil, Bitumen 50/70 undergoes a refining process that enhances its adhesive properties and resistance to aging. The bitumen’s chemical composition and physical properties make it an excellent binder for asphalt mixtures, ensuring the durability and longevity of paved surfaces.
QUALITY STANDARD:
Bitumen 50/70 is widely used in various construction and paving applications due to its balanced properties. Key uses include:
- Urban streets: Ideal for city roads and streets that experience moderate traffic volumes, providing a durable and smooth surface for vehicular and pedestrian use.
- Medium traffic roads: Suitable for roads that experience regular traffic, including commercial and residential areas, where a balance of hardness and flexibility is required.
- General road construction: Versatile enough for use in a wide range of road construction projects, from highways to local roads, ensuring consistent performance across different environments.
Bitumen 50/70’s intermediate properties make it suitable for regions with moderate climates, where it can effectively resist cracking in colder temperatures and softening in hotter conditions.
QUALITY STANDARD:
Bitumen 50/70 conforms to the European Standard EN 12591, which sets stringent requirements to ensure quality and performance. Key criteria include:
- Penetration: Ensures the bitumen’s suitability for various applications based on its hardness.
- Softening point: Indicates the bitumen’s performance under high-temperature conditions, ensuring it remains stable and functional.
- Flash point: A measure of safety, indicating the temperature at which the bitumen can ignite.
- Solubility: Ensures the bitumen is free from non-bituminous impurities, guaranteeing consistent performance.
- Compliance with these standards ensures that Bitumen 50/70 delivers reliable and predictable results in various construction and paving applications.
STORAGE:
Maintain storage temperatures between 150°C and 180°C to prevent hardening and ensure the bitumen remains workable.
Use steel containers or bitumen tanks that are designed to handle high temperatures and prevent contamination.
Ensure storage facilities are well-ventilated, dry, and protected from moisture to prevent oxidation and degradation.
Avoid prolonged storage at high temperatures and frequent temperature fluctuations, which can lead to the hardening and loss of essential properties.
