Description of Australian Grade Bitumen C170
Australian Grade Bitumen C170 is a standard viscosity-grade bitumen used in road construction and other applications of asphalt. It is produced according to Australian Standards (AS 2008-2020) and is intended for applications that require moderate stiffness.
C170 bitumen has a penetration value of about 60-80 (measured in tenths of a millimeter) and a viscosity of approximately 170 Pa.s at 60°C. This grade of bitumen provides a balance between flexibility and durability, hence best suited for use in the temperate climatic regions where roads are subjected to moderate thermal and mechanical stresses.
Application of Australian Grade Bitumen C170
Bitumen C170 is widely used in road maintenance, especially for sprayed sealing applications. Australian Standard bitumen C170, otherwise known as Class 170 bitumen, is highly penetrating and very sticky, thus it can hold tightly to the road surface.
Besides, it enables the pavement to regain its flexibility and avoid cracking, rutting, and fatigue. Apart from road maintenance, Bitumen C170 is also used for paving surfaces in areas where traffic loads are expected to be minimal.
It’s perfect for asphalt mixing, asphalt compaction, and spraying. It’s ideal for moderate traffic volumes and provides reliable performance at varying temperatures without becoming too brittle or too soft.
Use personal protective equipment (PPE’s) when handling. (i.e., Gloves, Eye Protectors).
Maintain safe heating temperatures when using this product.
Avoid contact with skin, eyes, and clothing.
Avoid breathing vapor, spray or mists when applying.
Quality Standard
Australian Grade Bitumen C170 is meticulously engineered to comply with the stringent requirements established by the Australian Standard AS2008. Our comprehensive Quality Check (QC) process ensures that the bitumen C170 meets the high standards of quality and performance required for your projects.
Conclusion
In the end, bitumen C170 plays a vital role in many industries because of its special properties and wide application areas. Though there are problems and environmental concerns, ongoing research and development studies open a bright perspective for a greener and more efficient future of bitumen C170.
