Use of Geosynthetics in Indian Railways
Geosynthetics are widely accepted and used by the Indian Railways for various applications , like Ground Improvements , Base stabilization for high embankments over soft soil , track bed stabilization , track drainage , steep slope stabilization , erosion control etc . Use of geosynthetics result in significant savings , improved performance on both short term and long-term basis .
The Indian Government has set a capex target of Rs 1.48 trillion for 2018-19 on Development of Railway Infrastructure . Dedicated freight corridors and high-
speed corridors are also being planned which will entail heavy axle loads and will require railway tracks with stable track which increases the demand new technology which help to give the best quality of railway tracks with optimize design and increase the speed of construction , the use of good quality of geosynthetic materials for construction of new tracks . Here in this article we will focus on Track bed stabilization using PP Biaxial Geogrid
Problems faced during Railway Track Construction
In Railways , the Train wheel load is always in the same position andeach train when passes produce fast cycles of loading and unloading ( i . e . Pressure and De-pressure ), which causes fast degradation of the railway structure due to deformations .
