REJUPAVE is an indigenous technology developed by the CSIR-Central Road Research Institute (CSIR-CRRI), primarily used for constructing and maintaining bituminous roads in high-altitude areas, particularly under low and sub-zero temperature conditions. It is a bio-oil-based asphalt modifier that significantly reduces the heating requirement of bituminous mixes while preserving their temperature during transit. This eco-friendly technology has been successfully implemented by the Border Roads Organisation (BRO) at strategic locations like the Sela Road Tunnel and LDY Road Section near the Indo-China border in Arunachal Pradesh. The technology addresses major challenges in road construction in difficult terrains and contributes to the operational capacity improvement of defence forces and all-weather connectivity in remote regions.
