Australian Standard Bitumen Class-320

Australian Standard Bitumen Class-320 Supplier and Exporter

Australian Standard Bitumen Class-320 is a paving grade bitumen classified under the Australian Standard system, distinct from penetration grading, viscosity grading (VG, AC, AR), and the Superpave Performance Grade system. The “320” designation reflects a specific Australian Standard classification and should not be interpreted as a penetration value, viscosity value, or PG temperature grade without verified technical confirmation. Class-320 sits toward the firmer end of the Australian Standard paving bitumen range, generally associated with binder characteristics relevant to demanding pavement applications. Class-320 specifications and technical properties, including consistency, viscosity, and other quality parameters, depend on the applicable standard, so buyers should confirm exact values through the relevant test documentation. The binder’s properties can contribute to pavement performance when correctly selected and incorporated into an appropriately designed asphalt mixture. This grade is commonly used in asphalt production and road construction, and may be considered for highway construction, medium to heavy traffic pavement applications, and heavy duty infrastructure projects, with airport pavements included where technically appropriate. Selecting Class-320 or another binder grade requires evaluating traffic loading, climate, pavement design, and asphalt mix specific to each project. Turkey Bitumen Supplies Australian Standard Bitumen Class-320 to international importers, distributors, contractors, and procurement teams, supporting export orders around project specific requirements and technical documentation.

Frequently Asked Questions

Australian Standard Bitumen Class-320 Supplier and Exporter

What is Australian Standard Bitumen Class-320?

Australian Standard Bitumen Class-320 is a paving grade bitumen classified under the Australian Standard system, commonly used in asphalt production and road construction where its properties meet project requirements.

What does Class-320 mean in Australian Standard bitumen classification?

Class-320 refers to a specific classification within the Australian Standard system for bitumen, which uses its own methodology and is not directly equivalent to penetration, viscosity, or PG grading systems.

What are the main applications of Class-320 Bitumen?
Class-320 Bitumen is commonly used in asphalt production and road construction, with highway construction and heavy-duty infrastructure projects also considered depending on project requirements.
Is Class-320 Bitumen suitable for road construction?

Class-320 is commonly used for road construction where its binder characteristics meet the applicable project specifications and design requirements.

Is Class-320 suitable for medium- to heavy-traffic roads?

Class-320 may be considered for medium- to heavy traffic roads where its properties align with the pavement design, traffic loading, and applicable specifications.

Is Class-320 Bitumen used in asphalt production?

Yes, Class-320 is commonly used in asphalt production where its binder characteristics support the intended asphalt mixture design and project requirements.

Is Class-320 suitable for highways and airport pavement applications?
Class-320 may be considered for highway construction and, where technically appropriate, airport pavement applications, subject to engineering evaluation and applicable design standards.
What are the important Class-320 Bitumen specifications?

Specifications generally address consistency, viscosity, and other quality parameters defined under the applicable Australian Standard. Buyers should confirm exact figures through the supplier's test certificate for their order.

How does Class-320 differ from penetration, VG, AC, AR, and PG bitumen grades?

Class-320 follows the Australian Standard classification methodology, which differs from penetration grading, viscosity grading systems (VG, AC, AR), and the Superpave Performance Grade system used in other regions.

How can international buyers request a Class-320 Bitumen quotation?

Buyers can contact Turkey Bitumen with their required quantity, destination port, and project details to receive a quotation along with relevant technical information for Australian Standard Bitumen Class-320.
