Bitumen 40/50 Supplier for Road Construction and Asphalt Applications

Bitumen 40/50 is a semi-soft type of penetration grade bitumen. It mainly supports road building and asphalt pavement work. Because it has strong thickness and bonding power, it fits well in many construction projects. Moreover, this paving grade bitumen lasts long and handles tough weather and heavy traffic conditions effectively.

Bitumen 40/50 Manufacturing Process

Manufacturers make Bitumen 40/50 from refined crude oil and remove light compounds to produce a thick and strong binder. Then, they use modern systems to keep the quality consistent and meet global standards. As a result, this bitumen works well in many construction and industrial projects.

Thermoplastic Nature

One of the key characteristics of bitumen 40/50 is its thermoplastic behavior. This means the bitumen softens when heated and hardens upon cooling, allowing it to adapt to temperature fluctuations during paving and service life. This property enhances workability during mixing and compaction and contributes to the long-term performance of roads.

Key Technical Specifications

Bitumen 40/50 typically has the following physical properties:

• Penetration @ 25°C: 40–50 dmm

• Softening Point: 52–60°C

• Ductility @ 25°C: Minimum 100 cm

• Specific Gravity @ 25°C: 1.01–1.06

• Flash Point: Minimum 250°C

• Solubility in CS₂: 99.5% minimum

These specifications confirm its suitability for high-performance pavement applications and compliance with international standards such as ASTM D946 and AASHTO M20.

HS Code and CAS Number for Bitumen 40/50

In international trade, buyers and sellers use HS Code 27132000 to classify Bitumen 40/50 as petroleum bitumen. Its CAS Number is 8052-42-4. These codes help with export paperwork, product labeling, and following trade rules in different countries. Including accurate HS and CAS codes helps streamline logistics and ensures smooth customs clearance.

Application of Bitumen 40/50

Bitumen 40/50 is widely used in:

• Highways and expressways

• Airport runways

• Heavy-duty industrial roads

• Asphalt concrete mixtures

• Waterproofing and foundation sealing

• Modified bitumen products (e.g., emulsions and cutbacks)

Its hardness and viscosity make it ideal for areas with high stress and traffic loads.

Comparison with Other Grades

Compared to softer grades such as bitumen 60/70 or bitumen 80/100, bitumen 40/50 offers:

• Greater resistance to rutting

• Better performance in warm climates

• Lower temperature susceptibility

• Enhanced mechanical stability

This makes it a preferred choice for regions experiencing high temperatures and heavy axle loads.
