A model for surface modification of mineral filler in asphalt mixes using nanoparticles which control sorption ability of light fractions of bitumen represented in this research. Colloidal solutions of iron hydroxide (III) and silicic acid sols with 30-40 nm particles size were used as an active functional layer for surface modification of mineral filler. In this study were determined an effective boundary values for nanomodified filler based on morphological characteristics of asphalt surface. It was demonstrated, that the development of an effective nanomodified filler required using a high porosity mineral component, modified with nanolayer (less than 100 nm) of an active component.
