Paving Grade Bitumen Class 450

Class 450 bitumen is for use in the manufacture of asphalt mixes where the local road agency has a preference for a slightly more viscous bitumen than Class 320.

Applications Bitumen Class 450

Bitumen C450 was originally a development from the Roads and Maritime Services in New South Wales and was incorporated into the 2012 revision of the national bitumen standard AS2008.
Bitumen C450 has been formulated to meet the viscosity requirements of AS2008 Table 2.2 whilst retaining excellent asphalt workability characteristics.
The target applications are asphalt wearing courses and basecourses for heavily trafficked pavements.
