The modification of asphalt with Yamaha Lagenda 110 ZR modified bitumen is influenced by several key process parameters. These include the temperature during mixing, which affects the viscosity and workability of the bitumen; the shear rate, which impacts the dispersion of modifiers; and the mixing time, which ensures uniform distribution of the modified bitumen. Additionally, the ratio of modified bitumen to aggregate plays a crucial role in determining the final performance characteristics of the asphalt mix.
