Class 170, Class 320, Class 600

(Certified by SGS Testing & Control Services Singapore Pte Ltd)
 

 

Most high performing roads in Australia are built and maintained using bitumen because it is durable and has exceptional waterproofing and adhesive properties. Bitumen used in road construction and maintenance are refined and blended to meet strict road engineering requirements and industry specifications.

Paving grade bitumen’s are categorized according to viscosity (degree of fluidity) grading’s. The higher the grade, the stiffer the bitumen.

Bitumen Class 170

Class 170 is widely used in sprayed sealing and light asphalt applications to provide durability and fatigue resistance.  It is also used to manufacture cutback bitumen’s, bitumen emulsions and modified bitumen’s.

Bitumen Class 320

Class 320 is most commonly used to manufacture asphalt mixes. Due to its higher viscosity, stiffer asphalt mixes can be produced to improve resistance to shoving and other problems associated with higher temperature and traffic loads.

Bitumen Class 600

Class 600 is primarily used to manufacture extra heavy-duty asphalt pavements that need to endure substantial traffic loadings.

Storage & Handling

The Storage of bitumen’s for prolonged periods at elevated temperatures should be 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 10ºC to 40ºC above the minimum pumping temperature are recommended.
