Rejupave Technology

• In order to improve operational capacity of the defence forces in the high-altitude areas along the IndoChina border, the Border Roads Organisation (BRO) will build bituminous roads using an indigenous technology, “Rejupave”.
• It has been developed by CSIR-Central Road Research Institute (CSIR-CRRI), India’s oldest and premier road research organisation.
• The ‘Rejupave’ technology has been successfully utilised by the BRO to produce low-temperature bituminous mixes for the construction of bituminous roads at Sela tunnel and LGG-Damteng-Yangste (LDY) road site at an altitude of 14,000 feet and 18,000 feet.

ABOUT REJUPAVE TECHNOLOGY

• The indigenous technology’s asphalt modifier is a bio oil-based product
• It is developed as a Bio-based eco-friendly product with 100% biooil.
• It brings down the production and rolling temperature of bituminous mixes by 30 degrees Celsius to 400 degrees Celsius
• It also assures negligible heat loss in the bituminous mix during transit, despite long haulage time amid snowfall.
• Using ‘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 eliminates the problem of increasing road levels due to overlay.
