The Shamli–Ambala Section (NH-344GM) of the Bareilly–Ludhiana Economic Corridor is a key infrastructure project under the Bharatmala Pariyojana Phase-I in Haryana. Executed on EPC mode, this six-lane access-controlled highway extends from Adhoya Musalmana village to Sadopur village in Ambala District. The project connects the Western Ambala Bypass with the Ambala–Chandigarh Highway through a greenfield alignment across predominantly plain terrain.
Passing through important locations such as Barara, Tandwal, Goga Medi, Ghaseetpur, Bihta, Khuddi, Panjokhara, and Khatoli, the corridor is designed to enhance regional connectivity, improve traffic movement, and support economic growth through faster and safer transportation infrastructure. The project utilized TechFab India’s pavement stabilization expertise to enhance structural performance and construction efficiency.
Managing construction timelines across a large greenfield alignment was a major challenge due to extensive earthwork activities, coordination across multiple project stretches, resource mobilization, and maintaining continuous construction progress while adhering to strict project schedules and quality requirements for the access-controlled highway corridor.
The project alignment encountered varying subsoil conditions across different stretches, creating challenges in maintaining pavement stability and structural integrity. Careful ground assessment, proper material selection, and suitable pavement stabilization measures were essential to achieve uniform performance, durability, and long-term reliability of the highway infrastructure.
Ensuring minimal disruption to nearby villages and local connectivity during construction was a key challenge. The project required effective traffic management, careful planning of construction activities, and coordinated execution to maintain access routes, reduce inconvenience to local communities, and ensure smooth project progress throughout the corridor.
The conventional approach to pavement design involves extensive use of granular aggregates, resulting in high consumption of natural resources and increased carbon footprint. To improve pavement performance while conserving aggregates, geogrid-reinforced pavement technology was adopted for the project. TechFab India proposed TechGrid PP3030, a biaxial polypropylene geogrid manufactured through a controlled punching and drawing process. The geogrid acts as a reinforced membrane, effectively resisting vertical loads while confining the subgrade soil. It enhances bearing capacity and intercepts potential failure surfaces under traffic loading. Reinforcement of the WMM and GSB layers reduced vertical deformation and rutting, thereby improving pavement stability, durability, and long-term structural performance.
The use of TechGrid PP3030 enabled optimization of the pavement design by improving load distribution and enhancing subgrade performance. The reinforced pavement structure reduced dependency on thick granular layers, leading to lower aggregate consumption and minimized excavation requirements. This approach not only optimized material usage but also reduced transportation demands, construction time, and overall environmental impact. The solution contributed to a more sustainable and cost-effective pavement system while maintaining the required structural strength and long-term pavement performance.
TechFab India successfully supplied TechGrid Geogrid for the project within the stipulated timeframe while meeting all required quality specifications. The geogrid performance, including LCR and MIF values, was evaluated and verified at the site as per project requirements. The reinforced pavement system supported efficient construction of the GSB and WMM layers, contributing to improved pavement performance and durability.
The completed work was executed to the satisfaction of the National Highways Authority of India (NHAI) and the Project Management Consultants, ensuring compliance with project standards and operational expectations.
