The 5th Rubber Modified Asphalt Conference outlines several key technical requirements for asphalt or bitumen modification. These include the use of specific rubber types, such as crumb rubber from tires, with defined particle sizes and processing methods. Additionally, the conference emphasizes the importance of compatibility with asphalt, performance testing standards (e.g., viscosity, elasticity), and environmental considerations. Compliance with relevant specifications and guidelines ensures enhanced durability, performance, and sustainability of modified asphalt products.
