The Border Roads Organisation (BRO) has successfully utilised an indigenous road construction technology ‘Rejupave’ to build high-altitude bituminous road sections at the Sela tunnel and LGG-Damteng-Yangste (LDY) road near the India-China border in Arunachal Pradesh.
About ‘Rejupave’
REJUPAVE is a liquid bio-based asphalt modifiercum rejuvenating agent.
- ‘Rejupave’ is developed by CSIR-Central Road Research Institute (CSIR-CRRI).
- The technology is beneficial in constructing high-altitude bituminous roads at low and sub-zero temperature conditions.
- This technology brings down the production and rolling temperature of bituminous mixes by 30 degrees Celsius to 400 degrees Celsius with negligible heat loss in the bituminous mix during transit, despite long haulage time amid snowfall.
- It will increase the working window of road construction companies of BRO and help us to build a robust road network at a faster pace under challenging conditions.
- The indigenous technology’s asphalt modifier is a bio oil-based product, which significantly lowers the heating requirement of bituminous mixes besides preserving the bituminous mix temperature during transit.
