Bitumen 50/70

Bitumen 50/70 is a commonly used grade, particularly in Mediterranean countries, where many refineries produce this type of bitumen. It is a soft penetration grade, primarily employed as a paving grade bitumen suitable for road construction, repair, and the production of asphalt pavements. The technical specifications of bitumen 50/70 are as follows:

– It is predominantly used in the manufacturing of hot mix asphalt for bases and wearing courses.

Differences between 50/70 and 70/100

The viscosity of bitumen 50/70 is higher compared to bitumen 70/100. This higher viscosity reduces the workability and compaction ability of bituminous mixtures. However, the use of bitumen 50/70 significantly increases the stability values at all binder contents due to enhanced cohesion within the mix.

Softening Point and Penetration

ATDM supplies pure petroleum grade bitumen, obtained through the process of passing hot air over vacuum bottom. The bitumen provided by ATDM Co. LLC is derived from the remnants of crude oil after cracking and the removal of hydrocarbons. Penetration grade bitumen 50/70 has a penetration value between 50-70 desi-millimeter and a softening point between 52-58°C. This grade exhibits a thermoplastic property similar to synthetic resin materials, becoming softer with heating and hardening upon cooling. Bitumen 50/70 possesses a notably strong viscosity in comparison to other grades.

Bitumen 50/70 is a widely used soft penetration grade suitable for paving applications in the Mediterranean region. It is employed in road construction, repairs, and the production of robust asphalt pavements. While it has higher viscosity and reduced workability, it enhances stability and cohesion in bituminous mixtures. ATDM supplies pure petroleum grade bitumen with specific penetration and softening point values, ensuring its quality and performance in various applications.

ATDM provides a guarantee for the quality of bitumen 50/70 by implementing various measures. These include arranging for international inspectors to oversee the loading process and ensure the quality and quantity of the product during vessel loading. Additionally, quality control (QC) measures are implemented through batch test reports before shipping.

ATDM guarantees that the quality of bitumen 50/70 meets the standards set by ASTM/EN 12591, ensuring compliance with international quality specifications for bitumen. By adhering to these rigorous quality control processes and standards, ATDM assures customers of the reliability and performance of the supplied bitumen 50/70.

ATDM implements specific quality control measures to ensure the high quality of bitumen 50/70. These measures include:

  1. International Inspection: ATDM arranges for international inspectors to be present during the loading process of bitumen 50/70 onto vessels. These inspectors closely monitor and verify the quality and quantity of the product, ensuring compliance with specified standards.
  2. Batch Test Reports: Before shipping, ATDM conducts batch tests on the bitumen 50/70. These tests provide comprehensive information about the specific properties and characteristics of each batch. By examining parameters such as penetration, softening point, viscosity, and other relevant factors, ATDM ensures that the product meets the required specifications.
  3. Compliance with ASTM/EN 12591: ATDM guarantees that the quality of bitumen 50/70 complies with the standards outlined by ASTM/EN 12591. These international standards define the requirements for bitumen used in road construction and specify parameters related to penetration, viscosity, softening point, and other essential properties.

By implementing these quality control measures, ATDM ensures that the bitumen 50/70 it supplies meets the necessary standards and consistently delivers the expected performance and reliability in various road construction applications.

Range Of Bitumen At ATDM

ATDM provides a range of bitumen grades to cater to various construction and infrastructure needs. The specific grades of bitumen offered by ATDM may include, but are not limited to:

  1. Penetration Grade Bitumen: This includes grades such as Bitumen 40/50, Bitumen 50/70, Bitumen 60/70, Bitumen 80/100, and others. Penetration grade bitumen is commonly used in road construction, asphalt pavements, and other applications.
  2. Viscosity-Graded Bitumen (VG Bitumen): This includes grades such as VG-10, VG-20, VG-30, and VG-40. Viscosity-graded bitumen is suitable for different temperature conditions and is used in various construction projects.
  3. Polymer-Modified Bitumen (PMB): ATDM may also offer polymer-modified bitumen, which is bitumen modified with polymer additives to enhance its performance properties such as elasticity, durability, and resistance to deformation.
  4. Cutback Bitumen: Cutback bitumen is a mixture of bitumen and a volatile solvent. It is used in applications where a lower-viscosity bitumen is required for easier application and curing.

It’s worth noting that the availability of specific bitumen grades may vary based on factors such as location, customer requirements, and market demand. It is advisable to contact ATDM directly to inquire about the precise bitumen grades they provide.
