After nearly 150 years of oyster habitat loss causing declines in fish number and water quality, Sydney Rock Oyster reef restoration Project aimed to re-establish oyster habitat throughout NSW estuaries.
Why Choose Our ARTC-Compliant Ballast?
Our 63–20mm ballast is crafted from high-quality Andesite source rock, renowned for its exceptional strength, durability, and low porosity. This superior material, combined with advanced mobile crushing and screening processes, enables us to meet or exceed ARTC’s stringent specifications.
Key Compliance Features:
- Particle Size Distribution
Precisely graded for optimal track stability, load transfer, and minimal settlement. - Bulk Density & Water Absorption
Reliable support and efficient drainage, thanks to confirmed direct density and low water absorption. - Particle Shape & Flakiness Index
Sharp, well-formed particles meet ARTC’s strict shape criteria, resulting in excellent interlock and reduced track movement. - Aggregate Crushing Value (ACV) & Los Angeles Value (LAV)
Verified toughness and resistance to heavy loads ensure longevity under high-pressure rail environments. - Resistance to Wear by Attrition & Weak Particles
Low levels of weak or friable materials ensure lasting track integrity and reduced maintenance needs.
Our Andesite source rock plays a crucial role in meeting these rigorous standards. Its inherent qualities of durability, high strength, and low porosity make it the ideal foundation for ballast material, enabling us to deliver products that exceed expectations.
