NEWS – 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

• Developed by Council of Scientific and Industrial Research-Central Road Research Institute (CSIR-CRRI)
• Effective in addressing challenges posed by low and sub-zero temperature conditions during road construction
• Difficulty of Construction in Himalayan terrain arises due to the need for elevated temperatures ranging from 160 to 170°C in a hot mix plant, leading to delays and inferior mix quality during transportation.
• BRO’s Project VARTAK has successfully implemented REJUPAVE technology to build high-altitude bituminous roads
• Indigenous technology significantly reduces the heating requirement of bituminous mixes, ensuring effective compaction for desired durability and performance
• Evident in its successful application at critical sites, including world’s highest Sela road tunnel and LGG-Damteng-Yangste (LDY) road section near Indo-China border in the state at altitudes of 14,000 feet and 18,000 feet, overcoming the challenges posed by sub-zero temperatures
• Technology adoption is a major milestone towards sustainable and efficient road construction that contributes to strategic goals of the Centre in enhancing border infrastructure

THE CENTRAL ROAD RESEARCH INSTITUTE (CRRI)

• Constituent laboratory of the Council of Scientific and Industrial Research (CSIR)
