ASTM 40-50 Penetration Grade Bitumen: Built for Heavy-Duty Roads & Infrastructure
High Hardness, Superior Load-Bearing Capacity & ASTM DM Compliance for Demanding Projects
What is ASTM 40-50 Bitumen?
ASTM 40-50 Penetration Grade Bitumen is a high-hardness bitumen designed for heavy-duty road construction and infrastructure projects. With a penetration range of 40–50 dmm and superior thermal stability
It delivers unmatched durability for
- High-traffic highways
- Urban Infrastructure
- Hot Mix Asphalt
- Rehabilitation Projects
- Airport runways
- Industrial Yards & Ports
Key Specifications
- Penetration Value (dmm): 40–50 (ASTM D5)
- Softening Point (°C): 52–60 (ASTM D36)
- Flash Point (°C): ≥ 230 (ASTM D92)
- Solubility in Trichloroethylene: ≥ 99% (ASTM D2042)
Compliance
- ASTM D946M | NFPA 30 | ASME BPVC
Why ASTM 40-50 Bitumen
Stands Out
1.Exceptional Load-Bearing Capacity
- Withstands heavy axle loads and high traffic volumes.
- Ideal for highways and airport tarmacs.
2.Thermal Stability
- Softening point of 52–60°C prevents rutting in hot climates.
3.Superior Adhesion
- Strong bond with aggregates and easy workability.
4.Fast Setting Time
- Reduces project timelines with quicker curing.
5.NFPA Fire Safety Compliance
- Flash point ≥ 230°C ensures safe storage and transport.
