Bitumen 30/40 Supplier
for Heavy Duty Road Construction

Bitumen 30/40 is primarily used for heavy-duty road construction in hot climate regions. This hard penetration grade asphalt binder is ideal for:

• Highways, expressways, and airport runways
• Industrial roads and ports
• Stone matrix asphalt (SMA) mixtures
• High-modulus asphalt for heavy traffic zones

Its superior resistance to rutting and deformation makes it the preferred choice for infrastructure projects where pavement longevity is critical in high-temperature environments.

Key differences:

• Penetration: 30/40 = 30–40 dmm (harder), 60/70 = 60–70 dmm (softer)
• Softening Point: 30/40 has higher (51–56°C) vs 60/70 (46–52°C)
• Climate: 30/40 for hot climates; 60/70 for temperate/cold regions
• Load Resistance: 30/40 offers superior resistance to heavy loads
• Price: 30/40 commands 8–15% premium over 60/70

Yes, perfectly suited. Bitumen 30/40 is specifically engineered for hot climate applications, providing excellent resistance to:

• High ambient temperatures (up to 50°C+)
• Surface softening and rutting under traffic
• Thermal cracking in extreme heat
• Deformation from slow-moving heavy vehicles

This makes it the standard choice for road projects in Middle East, North Africa, South Asia, and other high-temperature regions.

Bitumen 30/40 has a lower penetration value measured in decimillimeters (dmm). The penetration test measures how far a standard needle penetrates under specific conditions (100g, 5 seconds, 25°C).

Lower penetration = harder bitumen, achieved through:

• Refining process optimization
• Selection of appropriate crude oil feedstocks
• Air blowing or other hardening processes

The harder consistency provides superior performance under heavy loads and high temperatures.
