Highway and railway construction faces long-term challenges such as soil instability, water accumulation, differential settlement, and excessive maintenance costs. Geosynthetics have become essential in overcoming these issues, improving pavement performance and extending design life.
Applications:
Subgrade Reinforcement: Geogrids and woven geotextiles stabilize weak or saturated soils, improving load distribution and reducing rutting under heavy traffic.
Separation and Filtration: Geotextiles create a barrier between aggregates and subsoils, maintaining structural layers while allowing controlled water flow.
Drainage Enhancement: Geonets and drainage composites prevent water buildup, eliminating hydrostatic pressure and minimizing freeze–thaw cycles.
Retaining Walls and Embankments: Geocells and high-strength geogrids reinforce steep slopes and embankments, reducing the risk of failure.
Ballast and Railbed Protection: Nonwoven geotextiles filter fines and protect ballast from pumping effects in railway systems.
Benefits:
Reduces construction and maintenance costs
Increases infrastructure service life by 30–50%
Enables construction in difficult soil or climate conditions
Minimizes traffic disruptions due to repair cycles
Enhances safety and ride quality for road and rail users
