Bitumen C320 Description
Bitumen C320 is a paving grade bitumen manufactured to AS 2008 Table 2.2 and is suitable for medium to heavy asphalt applications as well as for heavy-duty and hot climate seals.
Bitumen C320 is primarily for use in asphalt, but can also be sprayed as a sealing binder for heavy-duty applications and in hot desert regions. In asphalt applications, appropriate mixture and pavement designs should be employed to maximize the performance of the asphalt layer in service.
Recommended handling data for asphalt applications are as follows:
|Mixing Temperature||Holding time at Mixing Temperature||Medium term storage temperature||Medium term storage time||Maximum safe handling temperature|
|165-175°C||14 days||130-150°C||30 days||185°C|
|Spraying Temperature||Holding time at spraying temperature||Medium term storage temperature||Medium term storage time||Minimum pavement temperature|
|170-185°C||7 days||130-150°C||30 days||15°C|
Health & safety
Viva Bitumen C320 is unlikely to present any significant health or safety hazard when properly used in the recommended application where good standards of industrial practice are maintained.

Bitumen, also known as asphalt in the United States, is a substance that forms through the distillation of crude oil. It has waterproofing and adhesive properties. Bitumen production through distillation removes lighter crude oil components, such as gasoline and diesel, leaving the “heavier” Asphalt behind. The producer often refines it several times to improve its grade.
