Bitumen 60/70
Bitumen 60/70 is a medium penetration grade with a penetration of 60–70 dmm at 25°C, specified to ASTM methods. It balances stiffness and flexibility, which is why it is one of the most widely specified grades for hot-mix asphalt in warm and temperate climates.
Where Bitumen 60/70 is used
Penetration grade bitumen is classified by how far a standard needle sinks into the binder at 25°C, measured in tenths of a millimetre. A lower number means a harder bitumen.

Conforms to ASTM D946
Supplied to ASTM D946 test methods. Cargoes are tested for penetration, softening point, ductility, flash point, solubility and thin-film oven ageing, with results on the certificate of analysis.

Storing Bitumen 60/70
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.
