Performance of Ballast Layer Reinforced with Geosynthetics in Terms of Heavy Axle Load Operation

Nowadays requirements for strength and stability of railway subgrade are increased. It is due to raising of train speed and axle load. Some sections of subgrade that were previously considered stable do not satisfy safety requirements. In this regard, superstructure reinforcing solutions need to be developed. This paper highlights ballast and subgrade reinforcement applications of geogrids in railway infrastructure. In recent years, geosynthetics are widely used for this purpose. Geosynthetics influence on the stress-strain state of subgrade is an important and extremely urgent problem. The paper describes recent research efforts in field studies, which helped to identify geosynthetics reinforcement influence on ballast layer.
