Class 600 bitumen is primarily used to manufacture extra heavy-duty asphalt pavements that need to endure substantial traffic loadings.
Applications bitumen C600
bitumen C600 is the hardest paving grade bitumen available in Australia and is mainly used to produce high modulus asphalt.Heavy duty asphalt pavements need to be designed to accommodate significant traffic loadings for up to 40 years without exhibiting structural failure and hence, need to be constructed using appropriate materials.
The load spreading characteristics of pavement layers are governed by their stiffness and C600 bitumen facilitates the production of high modulus asphalt.
