PENETRATION GRADE
ASTM 30/40
Penetration Grade Bitumen 30/40 is a high-quality asphalt product produced from the refining of crude oil. This bitumen grade is distinguished by its dark color and specific hardness, represented by its penetration value in tenths of a millimeter. The “30/40” designation indicates a harder consistency compared to softer grades, making it suitable for a variety of demanding road construction applications.
Why Choose Bitumen 30/40?
- Consistency and Hardness: The 30/40 grade reflects a harder consistency, offering enhanced resistance to deformation under traffic loads. This makes it ideal for high-traffic and heavy-load applications.
- Thermal Stability: This bitumen softens at a slower rate when heated, which is beneficial for maintaining structural integrity during high-temperature processes such as asphalt mixing and application.
- Adhesion and Durability: It provides excellent adhesion to aggregates and superior waterproofing properties, ensuring long-lasting performance and protection against moisture-related damage.
Key Uses of Bitumen 30/40:
Penetration Grade Bitumen 30/40 is commonly used in various road construction and maintenance projects due to its robust properties:
- Hot Mix Asphalt Production: This bitumen grade is crucial in the production of hot mix asphalt, particularly for roads subjected to heavy traffic and high stress. It is used in both surface and base layers to ensure a durable and resilient road structure.
- High-Traffic Pavement Layers: Its hardness makes it suitable for use in pavement layers where greater resistance to deformation is required. This ensures the road surface remains stable and performs well under heavy loads.
- Road Surface and Base Courses: Bitumen 30/40 is employed in both the surface and base courses of roadways, providing a strong, stable foundation and a high-performance top layer.
Benefits:
- Increased Durability: The harder consistency of Bitumen 30/40 enhances the longevity and durability of road surfaces, making it suitable for areas with high traffic volumes and heavy loads.
- Improved Performance: Its resistance to deformation and excellent adhesive properties ensure a high-performing pavement that can withstand various environmental and operational conditions.
- Cost Efficiency: Although slightly more expensive, the enhanced durability and performance of Bitumen 30/40 can lead to lower long-term maintenance costs and improved road lifespan.
