Bitumen PG 64-22 – Asphalt Binder Equivalent to Penetration Grade 60/70

Bitumen PG 64-22 is a performance grade asphalt binder widely used in the construction of highways, expressways, airport runways, and other heavy-duty pavements. This grade has been engineered under the Superpave Performance Grading (PG) system, ensuring long-term durability under both high-temperature stress and low-temperature cracking. For buyers, importers, and infrastructure companies, PG 64-22 offers a reliable balance of quality, compliance, and cost efficiency for large-scale projects.

What is Bitumen PG 64-22?

Performance grade bitumen, also known as asphalt binder, is categorized based on its ability to withstand specific climate conditions. The designation PG 64-22 indicates:

• 64°C maximum pavement temperature the binder can resist without rutting.

• –22°C minimum pavement temperature where it remains flexible and resistant to thermal cracking.

This makes PG 64-22 an excellent choice for regions with moderate to high summer temperatures and cold winters, providing consistent performance across seasonal changes.

Key Applications in B2B Markets

Bitumen PG 64-22 is primarily purchased in bulk by:

• Highway and Road Contractors – for major road networks and urban highways.

• Airport Authorities – as a binder in runways and taxiways exposed to heavy loads.

• Municipalities and Infrastructure Developers – for bridges, urban streets, and expressways.

• Industrial Projects – such as container yards, ports, and logistic hubs.

Its ability to resist rutting, shoving, and low-temperature cracking ensures long-term pavement integrity, which is critical for government tenders and international projects.

Compliance and Standards

PG 64-22 is manufactured and tested according to AASHTO M320 standards under the Superpave system, ensuring compliance with internationally recognized specifications. Additional testing aligns with ASTM standards, including:

• ASTM D5 (Penetration)

• ASTM D36 (Softening Point)

• ASTM D92 (Flash Point)

This guarantees buyers and contractors a binder that not only meets but often exceeds technical requirements for durability and safety.

Packaging and Supply Formats

For international buyers and B2B procurement teams, PG 64-22 is available in multiple packaging options to meet different logistics requirements:

• Bulk Shipments via bitumen tankers or ISO containers.

• New Steel Drums (180–200 kg net) for containerized export.

• Jumbo Bags or Poly Bags for projects requiring flexible handling.

All shipments are provided with HS Code 27132000, customs documentation, and full quality certificates (COA, MSDS). Supply is available on FOB and CIF terms to major global ports.

Export and Logistics Considerations

Bitumen PG 64-22 is a high-demand product in regions with expanding infrastructure projects, including Asia, the Middle East, Africa, and Latin America. For bulk buyers, factors to consider include:

• Loading capacity – a 20-foot container can load up to 110–115 new steel drums.

• Port handling – availability of bulk terminals or drum storage.

• Transit protection – ensuring drums and bags are properly sealed against leakage.

Reliable suppliers can provide flexible shipping schedules and support with international trade compliance, making procurement easier for importers.

Comparison: PG 64-22 vs. Penetration Grade Bitumen 60/70

For buyers familiar with the penetration grading system, Bitumen PG 64-22 can be compared with Penetration Grade 60/70. Both products serve similar purposes in road construction, but there are key differences:

• Performance Definition: PG 64-22 is classified under the Superpave system, which measures performance at specific pavement temperatures (64°C to –22°C). Bitumen 60/70 is graded by its penetration value at 25°C (60–70 dmm), without directly accounting for climate extremes.

• Climate Suitability: PG 64-22 is designed for hotter summers and colder winters, making it more versatile for regions with wide temperature variations. Bitumen 60/70 is suitable for moderate climates but may face limitations in very hot or very cold conditions.

• International Projects: Large-scale government tenders and international infrastructure developments increasingly prefer performance grade binders (PG) because they ensure predictable behavior across different climates. Penetration grades like 60/70 are still widely traded, especially in Asia and Africa, but many engineers are transitioning to PG systems.

For bulk buyers, this means PG 64-22 offers higher assurance of pavement performance, while Bitumen 60/70 remains a cost-effective alternative in regions where Superpave specifications are not mandatory.
