Influence of subgrade soil characteristics on pavement durability and structural performance

Abstract

EN: Ukraine’s diverse geological conditions, particularly its widespread loess soils and soft water-saturated clays, pose significant challenges to pavement durability. This article examines how these soil types influence subgrade stability and pavement performance. Loess, known for its collapsible structure under moisture, and water-saturated clays, characterized by low shear strength, contribute to differential settlement, cracking, and premature pavement failure. Through case studies and geotechnical analyses, this study highlights the necessity of tailored engineering solutions - such as soil stabilization, enhanced drainage, and adaptive pavement design - to mitigate these risks in Ukraine’s infrastructure projects.
