Slope Stabilization for Bhutan’s P.T. Highway at Chumzom
Maccaferri’s ParaMesh reinforced soil system provided a sustainable and resilient retaining solution for the P.T. Highway at Chumzom, Bhutan, ensuring slope stability and safer mountain connectivity.
Explore how Maccaferri’s gabion and geotextile solution enhanced the sustainability and aesthetics of Ahmedabad’s Oxygen Park project.
The P.T. Highway at Chumzom, Bhutan, passes through challenging Himalayan terrain, where steep hill slopes, unstable ground conditions and complex mountainous geometry create significant risks for road safety and infrastructure performance. In such environments, retaining structures must not only ensure long-term stability but also adapt to site constraints, slope stabilization requirements, and the need for faster execution. Conventional rigid retaining structures often face limitations in these conditions due to constructability challenges, higher material dependency, and reduced adaptability to natural terrain behaviours.
To address these challenges, Maccaferri’s ParaMesh reinforced soil system was adopted as a sustainable and resilient solution for hillside road retention. The system incorporated Terramesh units with gabion fascia and ParaLink monoaxial geogrids, providing structural stability, flexibility, and improved performance in demanding mountain conditions. BioMac biodegradable geomat was also used for slope protection, supporting surface stabilization and environmental integration. Selected over conventional RCC retaining structures, the solution enabled faster construction, enhanced sustainability and improved adaptability, contributing to safer and more resilient mountain highway connectivity in Bhutan.
