Rejupave Technology at Indo-China border



Source: TOI

 Context: The Border Roads Organisation (BRO) plans to enhance the operational capacity of the defence forces along the Indo-China border in Arunachal Pradesh by using an indigenous technology called “Rejupave.


What is Rejupave?

Developed by CSIR-Central Road Research Institute (CSIR-CRRI), Rejupave is a bio-oil-based asphalt modifier that reduces the heating requirement of bituminous mixes and preserves their temperature during transit. This technology addresses the challenges of constructing and maintaining bituminous roads in high-altitude areas during low and sub-zero temperatures.

The BRO has successfully applied Rejupave at the world’s highest Sela road tunnel and LDY Road section near the China border in Arunachal Pradesh. The technology is developed using a Bio-based eco-friendly product with 100% biooil.


About Sela Road Tunnel: 

The Sela Tunnel has been excavated below the Sela Pass; a high-altitude mountain pass situated at an elevation of 4,200 meters (13,800 feet) above sea level. This tunnel aims to provide “all-weather” connectivity to Tawang, a remote and strategically significant district in the region. It will be the world’s longest bi-lane tunnel at an altitude above 13,000 feet.


Indo-China Border:

India shares a total boundary of around 3,488 km with China (the second largest after Bangladesh). The Sino-Indian border is generally divided into three sectors namely: Western sector, Middle sector, and Eastern sector. 5 states viz. Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh share a border with China.
