Built for Aussie Roads, Backed by BlackRock Bitumen
At BlackRock Bitumen, we take pride in delivering high-performance Australian Standard Bitumen (AS 2008)—engineered to endure the harsh conditions of Australia’s roads. From scorching outback highways to bustling urban streets, our bitumen ensures long-lasting durability and superior performance.
Why Australian Standard Bitumen (AS 2008) Matters
Australian roads face extreme weather, heavy freight loads, and long distances, demanding materials that won’t fail under pressure. AS 2008 sets the benchmark for residual bitumen used in pavements, ensuring:
Optimal viscosity for workability in varying climates
High resistance to deformation under heavy traffic
Long-term durability against cracking and aging
Consistent quality across all batches
Why BlackRock Bitumen Stands Out
Applications Beyond Roads
While AS 2008 bitumen is primarily for pavements, its uses extend to:
Airport runways – High-load resistance for aviation demands
Industrial flooring – Tough, long-lasting surfaces for warehouses
Bridge deck waterproofing – Protection against moisture damage
Car parks & driveways – Smooth, crack-resistant finishes
Technical Excellence – How We Ensure Quality
Every batch undergoes rigorous testing to meet AS 2008 specifications, including:
Viscosity at 60°C & 135°C – Ensures proper mixing and compaction
Penetration (25°C) – Verifies hardness and consistency
Flash Point (Safety) – Confirms safe handling temperatures
Ductility – Measures flexibility under stress
Penetration Grade Bitumen
Penetration Grade Bitumen is classified by a needle penetration test, indicating its hardness.
Viscosity Grade Bitumen
Classified by viscosity at high temperatures, indicating resistance to flow.
CutBack Bitumen
Bitumen mixed with petroleum solvents to lower viscosity for easier use, especially in cold conditions.
Bitumen Emulsion
A stable mixture of bitumen and water, often with an emulsifier, used for various paving applications.
