Which factors affect modified polymer asphalt in asphalt or bitumen modification systems?

Several factors influence modified polymer asphalt in bitumen modification systems. Key factors include the type and concentration of the polymer used, the compatibility of the polymer with the asphalt, the processing temperature and time during mixing, and the shear forces applied. Additionally, the base asphalt’s properties, such as viscosity and chemical composition, play a crucial role. Environmental conditions and intended application also affect the performance and durability of the modified asphalt.
