Paving Grade Bitumens
BP Bitumen is committed to delivering the highest quality products that perform on the road.
Bitumen ClassificationsMost high performing roads in Australia are built and maintained using bitumen because it is durable and has exceptional waterproofing and adhesive properties. Bitumens used in road construction and maintenance are refined and blended to meet strict road engineering requirements and industry specifications.
Paving grade bitumens are categorised according to viscosity (degree of fluidity) gradings. The higher the grade, the stiffer the bitumen.
BP Bitumen Class 170Class 170 is widely used in sprayed sealing and light asphalt applications to provide durability and fatigue resistance. It is also used to manufacture cutback bitumens, bitumen emulsions and modified bitumens.
BP Bitumen Class 320A popular bitumen grade for the manufacture of asphalt mixes, BP Class 320 produces asphalt which is stiffer than those prepared using BP Class 170 bitumen and this gives improved resistance to "shoving".
BP Bitumen Class 600Class 600 is primarily used to manufacture extra heavy-duty asphalt pavements that need to endure substantial traffic loadings.
Storage & HandlingThe storage of bitumens for prolonged periods at elevated temperatures should be avoided as quality may be adversely affected. As a general rule, bitumen should be stored at the lowest temperature that enables practical use.
For normal operations, such as blending and transferring liquid bitumen, temperatures of 10°C to 40°C above the minimum pumping temperature are recommended.
