Therefore, it’s crucial to understand how Bitumen 60/70 and Bitumen 80/100 each respond to different climatic conditions.

Bitumen 60/70 in Different Climates:

Bitumen 60/70 is most suitable for warmer climates due to its higher softening point. This means it can withstand higher temperatures without becoming excessively soft or losing its structural stability. It is less prone to rutting or deformation under high temperatures, which is common in warmer regions.

However, in colder climates, the higher viscosity of Bitumen 60/70 could lead to difficulties during application as it can become too rigid. This could potentially lead to cracking under extreme cold or heavy load.

Bitumen 80/100 in Different Climates:

On the other hand, Bitumen 80/100 is softer and more flexible, making it a better choice for colder climates. It offers greater workability and ease of application in colder temperatures due to its lower viscosity. It also shows superior resistance to cold cracking.

However, in warmer climates, Bitumen 80/100 can become too soft and may be more susceptible to deformation or rutting under high traffic loads or high temperatures. This may lead to shorter lifespan and increased maintenance needs.

In summary, when choosing between Bitumen 60/70 and Bitumen 80/100, it’s essential to consider the local climate conditions. Bitumen 60/70 is generally more suitable for hot climates and high-traffic areas, while Bitumen 80/100 is more appropriate for colder climates and less demanding applications.
