Rejupave Technology : Border Roads Organisation
The Border Roads Organisation (BRO) has utilised road construction technology i.e. Rejupave technology 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.
- Rejupave Technology is developed by India’s oldest and premier road research organisation, CSIR-Central Road Research Institute (CSIR-CRRI).
- It 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.
- This 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.
- Rejupave’ asphalt modifier in cold climatic regions will have improved long-term durability and better resistance to thermal cracking under low-temperature conditions.
- It also brings down the greenhouse gas emissions in the pristine eco-sensitive mountainous environment of Arunachal Pradesh.
