Description Of Bitumen C170

Bitumen C170 is a paving grade bitumen manufactured to AS 2008 Table 2.2 and is suitable for standard sealing and lightly trafficked asphalt applications.

Applications Of Bitumen C170

Bitumen C170 can be used for all standard spray sealing and lightly trafficked asphalt applications.

Asphalt recommendations

Mixing Temperature Holding time at Mixing Temperature Medium term storage temperature Medium term storage time Maximum safe handling temperature
  140-165°C   14 days   130-150°C   30 days 175°C

Sealing recommendations

Spraying Temperature   Holding time at spraying temperature Medium term storage temperature Medium term storage time Minimum pavement temperature
  170-180°C   7 days   130-150°C   30 days 15°C

During sealing operations, it is normal practice to add cutter oil to the bitumen to reduce binder viscosity to a level at which effective wetting and adhesion of the cover aggregate can take place. The quantity of cutter oil added to the bitumen depends upon the pavement temperature, the daily traffic and the nominal size of the cover aggregate. Basic cutting practice for Viva Bitumen C170 bitumen should be as follows:

Parts cutter per 100 parts bitumen measured at 15°C


Temperature (°C)  

Traffic (veh/lane/day)

Nominal Aggregate Size:

10mm or greater

Nominal Aggregate Size:

7mm or less

  15 to 20 low (<100) med (100 – 1500) high (>1500) 7-8 5-6 4 7-10 6-8 5-6
  20 to 25 low med high 7-8 5-6 4 7-10 6-8 5-6
  26 to 35 low med high 4-6 2-4 2-3 6-8 5-7 4-6
  >36   all   0-2   0-3

Health & safety

Bitumen C170 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. Further guidance on Product Health and Safety is available on the relevant Material Safety Data Sheet.
