VISCOSITY GRADE BITUMEN
AC Standard – 30
Asphalt Cement AC-30 is a high-performance, high-viscosity bitumen grade designed for road construction and maintenance in very hot climates. It offers exceptional durability, flexibility, and resistance to deformation, making it ideal for constructing high-traffic roads and heavy-duty pavements. AC-30 bitumen is known for its superior binding properties, ensuring that pavements can withstand extreme environmental stresses and heavy traffic loads, providing a reliable and long-lasting solution for infrastructure development.
USES:
AC-30 bitumen is suitable for a wide range of road construction and maintenance applications, particularly in regions with very hot climates. Its high viscosity and performance characteristics make it ideal for:
Hot Mix Asphalt for High-Temperature Regions: AC-30 is extensively used in hot mix asphalt for constructing smooth and durable road surfaces in very hot climates. Its binding properties ensure that the aggregates are well-coated, resulting in a high-quality pavement.
Heavy-Duty Pavements: AC-30 is an excellent choice for constructing pavements that need to bear heavy loads, such as those in industrial areas, airports, and highways.
Bituminous Macadam and Dense Graded Bituminous Mixes: AC-30 provides a strong and stable base for road surfaces, making it suitable for dense graded bituminous mixes.
Waterproofing and Damp-Proofing: AC-30’s water-resistant properties make it suitable for waterproofing applications, protecting structures from water infiltration and damage.
KEY FEATURES
AC-30 bitumen is characterized by several key features that make it a preferred choice for various road construction and maintenance applications:
Very High Viscosity and Stability: AC-30 has a very high viscosity that ensures stability and resistance to deformation in very hot climates. This makes it suitable for high traffic roads and heavy-duty pavements.
Superior Binding and Adhesion: AC-30 provides excellent adhesion to aggregates, ensuring a strong and durable bond that enhances the structural integrity of the pavement.
Waterproofing Properties: The waterproofing properties of AC-30 protect the underlying layers from water infiltration, preventing damage and extending the lifespan of the pavement or structure.
Durability: The superior binding properties and resilience of AC-30 ensure that pavements constructed with this grade of bitumen can withstand varying loads and environmental conditions, providing long-term durability.
TECHNICAL SPECIFICATIONS
AC-30 bitumen is produced to meet stringent technical specifications set forth by the ASTM D 3381, ensuring consistent quality and performance. Key technical parameters include:
Penetration Value: AC-30 has a penetration value of 40-60, indicating its stiff consistency suitable for very hot climates and high traffic conditions.
Viscosity: AC-30 bitumen has a viscosity of 2400-3200 poise at 60°C, ensuring its suitability for very hot regions and ease of application.
Softening Point: The softening point of AC-30 is typically around 60-70°C, ensuring it remains stable and effective at higher temperatures.
Ductility: AC-30 exhibits high ductility, allowing it to stretch and deform without breaking, which is crucial for withstanding the stresses of traffic loads and temperature fluctuations.
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.
