Several factors influence nanoclay modified asphalt materials in bitumen modification systems. These include the type and concentration of nanoclay used, the dispersion method, and the interaction between nanoclay and bitumen. Temperature during mixing and curing also plays a crucial role, as it affects the viscosity and flow properties of the asphalt. Additionally, the compatibility of nanoclay with the bitumen matrix can significantly impact the mechanical properties and durability of the modified asphalt.
