PENETRATION GRADE
ASTM 70/100
Penetration Grade Bitumen 70/100 is a high-quality asphalt product derived from the refining of crude oil. This bitumen grade is noted for its dark color and specific hardness, which is measured by its penetration value in tenths of a millimeter. The “70/100” designation signifies a softer consistency compared to harder grades, making it ideal for a variety of road construction and maintenance applications where flexibility and workability are crucial.
Why Choose Bitumen 70/100?
- Consistency and Flexibility: The 70/100 grade indicates a softer consistency, which provides greater flexibility and ease of application. This makes it well-suited for environments where a higher degree of workability is needed.
- Thermal Response: This bitumen softens at a relatively higher temperature, which facilitates easier mixing and laying during asphalt production and application processes.
- Adhesion and Waterproofing: It offers excellent adhesive properties for bonding with aggregate materials and superior waterproofing capabilities, ensuring a durable and long-lasting road surface.
Key Uses of Bitumen 70/100:
Penetration Grade Bitumen 70/100 is commonly used in various aspects of road construction and maintenance due to its versatile properties:
- Hot Mix Asphalt Production: This bitumen grade is used in producing hot mix asphalt, which is applied to both surface and base layers of roads. Its softer consistency allows for effective mixing and placement, particularly in conditions requiring more flexibility.
- Pavement Layers: Its flexibility makes it ideal for use in pavement layers where a softer and more workable bitumen is advantageous, especially in climates with varying temperatures.
- Road Surface and Base Courses: Bitumen 70/100 is employed in both surface and base courses of roadways, providing a high degree of adaptability and resilience.
Benefits:
- Enhanced Workability: The softer consistency of Bitumen 70/100 ensures improved workability, making it easier to handle and apply during the construction process.
- Durability and Performance: Despite its softer nature, it maintains excellent adhesive and waterproofing properties, contributing to a durable and high-performing road surface.
- Versatile Usage: Its properties make it suitable for a wide range of road construction projects, accommodating various traffic conditions and environmental factors.
