PENETRATION GRADE
ASTM 10/20
Penetration Grade Bitumen 10/20 is a high-performance asphalt product produced from the refining of crude oil. This bitumen grade is noted for its dark color and specific properties that make it suitable for various road construction and asphalt applications. The term “penetration grade” refers to the bitumen’s hardness and its ability to penetrate under a standardized load, with “10/20” denoting its penetration range in tenths of a millimeter.
Why Choose Bitumen 10/20?
- Consistency and Hardness: The 10/20 grade indicates a medium-soft consistency, which allows it to be flexible and durable while maintaining a good balance between stiffness and workability.
- Thermal Response: This bitumen softens gradually when heated, which is ideal for processes that involve high temperatures, such as asphalt mixing and laying.
- Adhesion and Waterproofing: It offers excellent adhesion to aggregates and superior waterproofing, which helps to protect road surfaces from moisture damage and enhances the overall longevity of the pavement.
Key Uses of Bitumen 10/20:
Penetration Grade Bitumen 10/20 is extensively used in various aspects of road construction and maintenance:
- Hot Mix Asphalt Production: This bitumen is a critical component in the production of hot mix asphalt. It is mixed with aggregate materials to form a durable and flexible asphalt that can be used for both base and surface layers of roadways.
- Pavement Design: Due to its high viscosity, Bitumen 10/20 allows for the design of thinner asphalt layers. This feature is beneficial because it can lead to a reduction of up to 30% in the total amount of bitumen required compared to thicker layers, while still maintaining strong performance.
- Surface and Base Courses: It is used in both the base and wearing courses of roads, ensuring that the final pavement is resilient to traffic loads and environmental conditions.
Benefits:
- Enhanced Pavement Durability: By using Bitumen 10/20, road surfaces benefit from increased durability and resistance to wear and tear.
- Cost Efficiency: The ability to use thinner layers of asphalt without compromising quality can result in cost savings on materials and construction.
- Improved Performance: The bitumen’s properties contribute to better road performance, including resistance to cracking and deformation under traffic loads.
