Nanotechnology, Soil stabilization, Pavement engineering, Nanosilica, Intelligent geotechnicsAbstract
Nanotechnology has emerged as a transformative approach for enhancing the performance of subgrade soils and pavement materials through nanoscale modification in their physicochemical and mechanical behavior. This technical note represents various aspects of the nanomaterials in subgrade stabilization and pavement engineering, covering flexible and rigid pavements. Nanoparticles improve soil performance through hydration and pozzolanic reactions which subsequent result in void filling and surface modification to produce a dense soil matrix. In flexible pavements, nanomaterials enhance rutting resistance, fatigue life, moisture stability, and optical properties of asphalt binders. In rigid pavements, nanosilica and related additives refine microstructure, strengthen the interfacial transition zone, and significantly improve strength and durability of concrete. The note further highlights environmental benefits, cost efficiency, durability enhancement, and emerging role of intelligent modeling and data-driven methods for optimizing nanomaterial performance. Overall, nanotechnology offers a sustainable, high-performance, and future-ready solution for subgrade stabilization and pavement engineering applications.
