Several process parameters significantly influence polymer modified asphalt during the modification of bitumen. Key factors include the type and concentration of polymer used, the temperature during mixing, and the shear rate applied. Higher temperatures can enhance polymer dispersion, while optimal shear rates ensure uniform mixing. Additionally, the duration of mixing affects the polymer’s interaction with the asphalt, impacting the final properties such as viscosity, elasticity, and resistance to deformation. Proper control of these parameters is crucial for achieving desired performance characteristics.
