Enhancing Pavement Performance Through Organosilane Nanotechnology: Improved Roughness Index and Load-Bearing Capacity
Year: 2025
Type: article
Abstract: The growing demand for sustainable road infrastructure requires innovative materials that enhance soil stabilization while minimizing environmental impact. This study explores the application of organosilane-based nanotechnology to improve the structural performance and durability of road corridors in Peru, offering an alternative to conventional stabilization methods. Laboratory evaluations show that the modified soil exhibits a more than 100% increase in the California Bearing Ratio (CBR), while expansion remains below 0.5%, significantly reducing moisture susceptibility. Asphalt mixtures incorporating nanotechnology-based adhesion enhancers achieved a Tensile Strength Ratio (TSR) above 80%, ensuring resistance to moisture-induced damage. Non-destructive evaluations, including the Dynamic Cone Penetrometer (DCP) and Pavement Condition Index (PCI) tests, confirm long-term durability and enhanced load-bearing capacity. Additionally, statistical analysis of the International Roughness Index (IRI) shows a mean value of 2.449 m/km, well below the technical threshold of 3.5 m/km established by Peruvian regulations. Furthermore, IRI values from other countries are also referenced. This research highlights the potential of nanotechnology to enhance pavement resilience, optimize resource utilization, and promote greener construction practices.
