VISCOSITY GRADE BITUMEN
AC Standard – 10
Asphalt Cement (AC) 10 is a medium-viscosity bitumen grade designed for road construction and maintenance in warmer climates. It offers a balance of durability, flexibility, and resistance to deformation, making it ideal for constructing high-performance road surfaces. AC 10 bitumen is known for its superior binding properties, ensuring that pavements can withstand heavy traffic loads and environmental stresses, providing a reliable and long-lasting solution for infrastructure development.
USES:
AC 10 bitumen is suitable for a wide range of road construction and maintenance applications. Its medium viscosity and performance characteristics make it ideal for:
Hot Mix Asphalt: AC 10 is extensively used in hot mix asphalt for constructing smooth and durable road surfaces in warmer climates. Its binding properties ensure that the aggregates are well-coated, resulting in a high-quality pavement.
Bituminous Macadam and Dense Graded Bituminous Mixes: AC 10 is an excellent choice for dense graded bituminous mixes, providing a strong and stable base for road surfaces.
Pavements in High Traffic Areas: AC 10 is suitable for constructing pavements in high traffic areas, where the surfaces need to bear heavy loads and resist deformation.
Waterproofing and Damp-Proofing: AC 10’s water-resistant properties make it suitable for waterproofing applications, protecting structures from water infiltration and damage.
KEY FEATURES
AC 10 bitumen is characterized by several key features that make it a preferred choice for various road construction and maintenance applications:
Medium Viscosity and Stability: AC 10 has a medium viscosity that ensures stability and resistance to deformation in warmer climates. This makes it suitable for high traffic roads and heavy-duty pavements.
Superior Binding and Adhesion: AC 10 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 10 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 10 ensure that pavements constructed with this grade of bitumen can withstand varying loads and environmental conditions, providing long-term durability.
TECHNICAL SPECIFICATIONS
AC 10 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 10 has a penetration value of 70-100, indicating its medium consistency suitable for warmer climates and high traffic conditions.
Viscosity: AC 10 bitumen has a viscosity of 800-1000 poise at 60°C, ensuring its suitability for warmer regions and ease of application.
Softening Point: The softening point of AC 10 is typically around 50-60°C, ensuring it remains stable and effective at higher temperatures.
Ductility: AC 10 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.
