Bitumen C320
Class 320 bitumen is classified to AS 2008 by its viscosity at 60°C of 260–380 Pa·s. The most common Class grade for dense-graded asphalt on medium to heavily trafficked roads.
Where Bitumen C320 is used
AS 2008 classifies residual bitumen for pavements by viscosity at 60°C into Class grades, used by Australian, New Zealand and Pacific road authorities.

Storing Bitumen C320
Temperature: Keep paving grades between roughly 140°C and 170°C in working tanks, and store at the lower end for long holds. Avoid repeated heat-up and cool-down cycles.
Tanks: Use insulated, heated steel tanks with a closed vent system. Dedicate a tank to one grade, or clean it fully between grades to avoid cross-contamination.
Safety: Water and hot bitumen must never meet, because it causes violent foaming. Use heat-resistant PPE, and keep a dry, ventilated area with no ignition sources near the vents.
Shelf life: Bitumen hardens slowly under prolonged heat. Rotate stock, avoid holding it at peak temperature, and re-test before use after long storage.
