Design of Geogrid Stabilisation for Railway Ballast and Subballast

Railways face unique challenges on soft soils due to heavy loads exerted on the subgrade by passing trains.This can lead to rapid and repetitive loading, causing settlements that compromise railway integrity.To address this, reinforcing geogrids can be used to stabilize the railway base, extending its lifespan.This paper presents a methodology for designing geogrid stabilization systems tailored to railway ballast and subballast.Factors such as wheel loads, traffic frequency, and subgrade properties are considered in the design process, which adapts established principles from road base stabilization.By integrating these principles, the methodology aims to provide a systematic approach for effectively incorporating geogrids into railway infrastructure projects, ultimately enhancing stability and longevity.
