Review of chemical methods for road pavement stabilization: prospects for application in Uzbekistan

This article provides an overview of methods for stabilizing the subgrade soils of road pavements using nanomaterials and polymer additives. A theoretical‐comparative analysis is performed on both traditional stabilization methods and modern approaches that employ nanosilica, nanoclays, carbon nanotubes, and various polymers. The mechanisms of action of the stabilizers and their influence on the physico mechanical properties of soils are examined, along with the advantages and disadvantages of each method. Particular attention is devoted to the specific climatic and geological conditions of Uzbekistan. Based on an analysis of the literature and modeling results reported by both domestic and international researchers, recommendations are made for selecting optimal stabilization methods for different soil types and climatic zones in Uzbekistan. It should be noted that this study is a review and does not present the results of original experiments.
