What technical requirements define rubber modified asphalt conference for asphalt or bitumen modification?
Rubber modified asphalt requires specific technical standards to ensure optimal performance. Key requirements include the use of high-quality crumb rubber, typically from scrap tires, with a specified particle size and processing method. The blending temperature should be controlled to facilitate proper dispersion without degrading the bitumen. Additionally, the modified asphalt must meet performance criteria such as viscosity, elasticity, and temperature susceptibility, ensuring enhanced durability, resistance to cracking, and improved adhesion in various environmental conditions.
