Bitumen 50/70
Bitumen 50/70 is a medium paving grade with a needle penetration of 50–70 dmm at 25°C, produced and tested to the European standard EN 12591. 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 50/70 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 EN 12591
Supplied to EN 12591 (paving grade bitumens). Each cargo is tested for penetration, softening point, flash point, solubility and resistance to hardening (RTFOT), with results on the certificate of analysis.

Storing Bitumen 50/70
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.
