Frequently Asked Questions.
Our PG 70-40 bitumen is a high-performance asphalt binder designed for high-temperature stability and exceptional low-temperature crack resistance in extreme climates.
1. What is PG 70-40 bitumen?
PG 70-40 is a Performance Grade (PG) asphalt binder designed to perform at high pavement temperatures up to 70°C and low temperatures down to −40°C.
2. Where is PG 70-40 commonly used?
It is commonly used in:
- Cold and extreme climate regions
- Highways and expressways
- Bridges and pavements prone to thermal cracking
- Heavy-traffic roads exposed to wide temperature variations
3. Why is PG 70-40 considered a high-performance binder?
It offers excellent resistance to rutting at high temperatures and exceptional flexibility at very low temperatures, often achieved through advanced polymer modification.
4. What are the advantages of using PG 70-40?
- Outstanding low-temperature crack resistance
- Strong high-temperature stability
- Long pavement service life
- Reliable performance in extreme climates
5. How should PG 70-40 be stored and handled?
PG 70-40 should be stored in temperature-controlled heated tanks, avoiding prolonged overheating, and handled with clean equipment to maintain binder properties.
