Le bitume 50\/70 est le grade de p\u00e9n\u00e9tration de r\u00e9f\u00e9rence pour les routes en Europe. C’est celui que demandent les cahiers des charges fran\u00e7ais, belges et roumains, parce qu’il est d\u00e9fini par la norme europ\u00e9enne EN 12591.

The \u201c50\/70\u201d refers to the penetration: a standardised needle sinks between 50 and 70 tenths of a millimetre into the product at 25 \u00b0C. All the values below are measured according to the European (EN) test methods.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

50\/70 or 60\/70? How to choose<\/h2>\n

The two grades overlap almost entirely on penetration. The real difference is not the hardness, it is the standard cited in your specifications. The 50\/70 falls under the European standard EN 12591; the 60\/70 under the American standard ASTM D946, used in the Middle East, Africa and Asia. If your buyer is in Europe, ask for the 50\/70. If they work under an ASTM reference, it is the bitumen 60\/70<\/a>. We supply both.<\/p>\n

Applications<\/h2>\n

The 50\/70 is used mainly to produce hot-mix asphalt for base and wearing courses: urban roads, secondary roads, motorways, airport runways, industrial platforms. It performs well under heavy traffic in temperate European climates. It is also found in waterproofing membranes and as a base for emulsions.<\/p>\n
