Asphalt modified bodies for bitumen modification must meet several technical requirements. These include compatibility with various modifiers, resistance to temperature fluctuations, and durability under mechanical stress. The materials should ensure uniform dispersion of modifiers, maintain viscosity within specified limits, and exhibit low volatility. Additionally, the bodies should comply with environmental regulations and facilitate easy cleaning and maintenance. Proper insulation and sealing are also essential to prevent contamination and ensure consistent performance during the modification process.
