Nanoclay-modified asphalt materials are applied in asphalt or bitumen modification processes by incorporating nanoclay particles into the asphalt binder during the mixing phase. This is typically achieved through mechanical mixing or high-shear blending, which ensures uniform dispersion of the nanoclay within the binder. The addition of nanoclay enhances the mechanical properties, thermal stability, and resistance to deformation of the asphalt, resulting in improved performance and durability of the final pavement material.
