What does an increase in the temperature of asphalt during mixing typically lead to?

An increase in the temperature of asphalt during mixing typically leads to a potential loss of volatile components. When asphalt is heated, the viscosity decreases, allowing for easier mixing and better workability in the production of asphalt mixtures. However, this increase in temperature can also cause some of the lighter, volatile components of the asphalt to evaporate. These volatile components play a crucial role in the properties of the asphalt binder, influencing its performance in the final product.

Maintaining the appropriate temperature during mixing is essential to prevent excessive loss of these components, as it can affect the overall quality and durability of the asphalt mixture. Thus, managing temperature during mixing is not only critical for achieving proper consistency but also for preserving the integrity of the asphalt binder.

Working to control the levels of volatile substances is part of modern asphalt production best practices to enhance performance and longevity, so recognizing the potential for loss at elevated temperatures is key in the process of asphalt mixing and application.
