Transforming Rail Infrastructures with Geosynthetics

Stimulating economic prosperity through the advance of transportation infrastructure is the crux of bolstering cross-national partnerships. The economic boom generated by connecting societies and nations via highway and railway routes is mutually beneficial to governments and investors, encouraging a harmonized open market worldwide. ACE innovators seamlessly blend our geosynthetic materials with pavement sublayers to upgrade the bearing capacity and thus the service life of transportation routes traversing multifarious geological conditions. High strength ACETex® geotextiles for soil stabilization and reinforcement is a leading fabric applied in transportation constructions intercontinentally.

At a glance, ACE’s railway subgrade improvement project with ACETex® PP fabric in New Taipei City, Taiwan. Take a look below.

Use of ACETex® in Treatment of Railway Subgrade

Project Background
The intermittent vibrational loading from trains crossing the Raifung segment of the Taiwan Rail hazardously pumped fines from the subgrade into the ballast layer. The intermixed layers differentially settled and distorted the rail-sleeper connections, perilously threatening the lives of passengers on this route. The Taiwan Railway Administration (TRA) required an economic solution that would separate the ballast from the poor subgrade soil and reduce the original quantity of ballast added to the train tracks.

ACE Solution
A blanket of high tensile strength ACETex® PP woven and ACETex® nonwoven geotextile separated the weak subgrade from the new ballast layer, subsequently filtering out fines and preventing the intermixing of the railroad base courses.

Product: ACETex® PP, ACETex® NW
Solution: Subgrade Stabilization, Base Reinforcement

The Contribution
ACETex® geotextile fabric strengthens road and railway structures, bridging the flow between communities for stable economic growth and trade.
