Bitumen 60/70

The global paving grade for hot and temperate climates

Bitumen 60/70 is defined by penetration at 25°C of 60–70 dmm, a softening point of 49–56°C and ductility at 25°C of ≥ 100 cm, and it is the grade the majority of the world's highway tenders are written around. CBIL brokers it to EN 12591 (as 50/70 or 70/100 band material where the European standard applies), ASTM D946 and the Gulf and African road-authority specifications that mirror them, with flash point ≥ 250°C, solubility in trichloroethylene ≥ 99.0% and loss on heating ≤ 0.2%. The commercial variables that decide whether a lot is accepted at site are penetration, softening point and the retained penetration after RTFOT — not the brand on the drum — so every cargo we arrange ships against SGS or Intertek certification of the full spec sheet at load port.

A buyer picks 60/70 over 80/100 when the service temperature is high or the traffic loading is heavy: the harder binder resists rutting in summer pavement temperatures that would push a softer grade past its shear limit. Against 40/50 it is the more workable choice — 40/50 is a hot-climate, heavy-axle specialist that pays for its rut resistance with a real low-temperature cracking risk. That makes 60/70 the default across the Middle East, South Asia, Africa and southern Europe for dense-graded asphalt, and the grade contractors specify when they want one binder to cover a whole programme. Supply is structured on FOB, CFR and CIF terms from UAE, Bahrain, Iran and Singapore loading points, in new steel drums (150/180 kg), 300 kg jumbo bags, bitutainers or hot-bulk vessel, with documentation aligned to your destination's road-authority regime.
