What is the purpose of using additives in asphalt production?

The use of additives in asphalt production primarily serves to improve specific performance attributes. Additives are integral in enhancing the properties of asphalt mixtures to meet particular requirements for various applications. For example, certain additives can enhance the durability, flexibility, and resistance to temperature fluctuations of asphalt, which are crucial for road performance and longevity. They can also improve the resistance to deformation, cracking, and moisture damage, making the asphalt more reliable under various environmental and traffic conditions.

While changing color, reducing manufacturing time, or decreasing costs may be considered in some contexts of asphalt production, these factors are not the primary focus or purpose of using additives. The core objective remains centered on enhancing the practical characteristics of asphalt to ensure it meets the demands of its intended use.
