Bitumen 40\/50: the hard grade for hot climates and heavy traffic<\/h1>

The 40\/50 is the hardest of the common penetration grades in international trade. When a 60\/70 starts to rut under heat and heavy axles, the 40\/50 is the one specified. Typical markets: high heavy-goods traffic corridors, port and industrial areas, countries where ground pavement temperatures stay above 50\u00a0\u00b0C.<\/p>

At 25\u00a0\u00b0C, the standardised needle penetrates 40 to 50 tenths of a millimetre (ASTM\u00a0D5 \/ EN\u00a01426 test). The grade falls under ASTM\u00a0D946 and AASHTO\u00a0M20. ASTM<\/a> D5 \/ EN 1426). Le grade rel\u00e8ve de la norme ASTM D946 et de l\u2019AASHTO M20.<\/p>

Applications<\/h2>

Hot mix asphalt for base and wearing courses where resistance to deformation is paramount: national roads in hot climates, junctions and slow lanes, logistics platforms, airports. Its high softening point makes it markedly less prone to rutting than softer grades. The flip side: in cold climates it becomes brittle and cracks \u2014 it is not a universal grade.<\/p>

40\/50 or 35\/50?<\/h2>

Buying 40\/50 bitumen well for export<\/h2>\n

The choice of bitume 40\/50<\/strong> is justified above all in regions where service temperatures are high and where heavy traffic places strong demands on the pavement. Its greater hardness than the 50\/70 gives it better resistance to rutting, provided that laying respects suitable compaction temperatures. A discerning buyer therefore checks upfront that the grade is compatible with their climate and their specification.<\/p>\n

On the supply side, securing a lot of 40\/50 bitumen means confirming the refinery origin, obtaining a compliant certificate of analysis and framing the logistics through a clear Incoterm. For large volumes, an independent pre-shipment inspection provides an additional guarantee on the conformity of the delivered product, while a letter of credit secures settlement between the parties. bitume 40\/50<\/strong> means confirming the refinery origin, obtaining a compliant certificate of analysis and framing the logistics through a clear Incoterm.

Frequently asked questions<\/h2>

Why choose a 40\/50 rather than a 60\/70?<\/p>

For its resistance to rutting: heavy, slow or channelled traffic, and very hot pavements. If your climate and traffic are moderate, the 60\/70 is enough and is easier to work with.<\/p><\/div>

Does the 40\/50 require a higher application temperature?<\/p>

Yes, a harder grade is pumped and mixed at a higher temperature than a soft grade. The exact temperatures appear on the cargo\u2019s technical datasheet.<\/p><\/div>

Is it available in drums?<\/p>

Yes, 180 to 190 kg steel drums, about 110 drums per 20-foot container.<\/p><\/div><\/div>","protected":false},"excerpt":{"rendered":"
