Rs 44.5-Crore Road Reconstruction Project in Karsog Adopts Advanced FDR Technology
The Himachal Pradesh government is implementing a comprehensive road development policy to strengthen and enhance the durability of road infrastructure, with a special focus on improving connectivity to rural and remote areas. Under the third phase of the Pradhan Mantri Gram Sadak Yojana (PMGSY-III), the Public Works Department (PWD) is using the advanced Full-Depth Reclamation (FDR) technique for road construction and reconstruction in the Karsog subdivision of Mandi district. Four key roads are being reconstructed with a total investment of approximately Rs 44.50 crore.
Details of the Four Roads Being Upgraded
The four roads being reconstructed using FDR technology include the 17-km Kheel–Bhagalu road, the 11-km Kheel–Kufri Mahunag road, the 10-km Chalog–Bagaila road, and the 15-km Kelodhar–Syanj road. These roads serve as vital links for several remote villages in the Karsog region, and their reconstruction is expected to significantly improve access for residents, farmers, and businesses.
Understanding Full-Depth Reclamation (FDR) Technology
According to PWD officials, Full-Depth Reclamation is a modern and scientific method of road reconstruction. In this process, the existing damaged road layers are milled and recycled in full depth using specialised machinery. The reclaimed material is processed and stabilised to form a strong base layer, over which a new road surface is laid. This technique strengthens the entire pavement structure, ensures higher construction quality, and promotes sustainability by reusing existing materials instead of discarding them.
Unlike conventional repair methods that typically address only the surface layer, the FDR rehabilitates the full road structure, preventing recurring cracks and potholes caused by weaknesses in the underlying layers. This results in longer-lasting roads with reduced maintenance needs.
Environmental and Economic Benefits of FDR
Officials highlighted the environmental benefits of the FDR technique, noting that reuse of existing road material reduces the demand for fresh aggregates, minimises construction waste, and helps conserve natural resources. The technology also lowers the carbon footprint associated with transporting new materials and disposing of old debris. Economically, the FDR method can reduce construction costs by up to 30% compared to traditional reconstruction methods, according to industry estimates.
Official Statement on PMGSY-III Implementation
Ajay Raj Gupta, Executive Engineer of the PWD Karsog division, said, "Under the state government’s road development policy, roads constructed under PMGSY-III in the region are being developed and reconstructed using the FDR technology. Four major roads in the subdivision have already been reconstructed using this technique." He added that the department is committed to using innovative construction methods to ensure durable and sustainable road infrastructure in the region.
Impact on Rural Connectivity and Development
The improved roads will enhance connectivity for dozens of villages in the Karsog area, facilitating easier access to markets, healthcare facilities, schools, and other essential services. Better roads are also expected to boost local economic activities, including agriculture and tourism. The project aligns with the central government's vision of providing all-weather road connectivity to rural habitations under the PMGSY scheme.
