Bitumen C600 | Class 600 bitumen
Australian Standard Bitumen C600 is a high-viscosity paving bitumen designed for heavy-duty road construction and industrial pavement applications. This grade offers strong cohesion, excellent adhesion to aggregates, and superior resistance to deformation under high temperatures and heavy traffic loads. Its thick and stable nature makes it especially suitable for base and binder course asphalt layers where long-term structural strength is essential.
Manufactured in accordance with Australian standards, Bitumen C600 is tightly controlled for penetration, viscosity, purity, and flash point to ensure consistent quality and performance. It provides reliable resistance to oxidation and aging, helping to minimize cracking, rutting, and moisture damage over time. As a result, C600 contributes to longer pavement service life, reduced maintenance needs, and improved overall durability in demanding service conditions.
