Penetrating Bitumen
Penetrating Grads
Penetrating Bitumen for Road Construction
Penetrating bitumen plays a crucial role in road construction, ensuring durability and performance across different climates.
- In warmer regions, stiffer bitumen with a lower penetration grade is preferred for greater resistance to heat.
- In colder climates, softer bitumen with a higher penetration grade is used to enhance flexibility and prevent cracking.
