Geosynthetics for Railway Ballast Stabilization

Of foremost importance in the railways is the maintenance of

the substructure. Inadequate substructures can lead to track

degradation and decreased lifespans of the rail fastening

system, leading to decreased operational capacity and

increased maintenance cost.

A railroad track substructure basically has four components,

the ballast, sub-ballast, drainage, and subgrade. While the

ballast provides a strong trackbed, helps distribute loads, and

allows drainage, the sub-ballast is a barrier between the

ballast and subgrade, providing more strength in case of a

weak subgrade. The subgrade usually depends on the natural

environment, and effective drainage is essential to direct the

runoff water away from the track.

Role of Geosynthetics in the railway sector:

Whether it is new track construction or rehabilitation, there is

enormous use of geosynthetics like geogrids, geocomposites,

geocells, and geotextiles in the railway sector.

Geotextiles (resistant to

puncture and tear) help with

separating track layers

supporting structures of

different sizes and properties

and also preventing the

penetration of granular

particles onto the subgrade.

This helps maintain the

integrity of granular layers

and increases track life.

Ballast Stabilization: For reinforcement, geosynthetics like

geotextiles, geogrids, and geocells, when installed over

unstable or soft subgrades, improve efficiency by increasing

load bearing capacity and better stress distribution. This is

nothing but strengthening the railway ballast.

Ballast pockets are a common issue that leads to track

geometry degradation. These are depressions beneath the

ballast layer formed when ballast particles penetrate the

subgrade forming pockets collecting moisture. The presence

of ballast pockets warrants more track maintenance and

results in a lower operational capacity.

Improved and stabilized subgrade material, installation of

proper ballast drains to drain off the excess water, and

stabilizing the upper ballast are all remedial measures for

ballast pockets.

Geotextiles, with their permeability and retention properties,

also act as a filter layer allowing free movement of water

without disturbing or dislodging the subgrade.

Proper drainage is highly critical to prevent track

deterioration. Towards that end, geosynthetics like drainage

geocomposite that are resistant to mechanical damage are

useful when installed at relevant points. They provide cross-

track drainage, preventing the accumulation of water.

Geosynthetics offer strength to the railway substructure

resulting in stronger, safer, and robust tracks at economical

prices.
