In order to improve operational capacity of the defence forces in the high-altitude areas along the Indo-China border in Arunachal Pradesh, the BRO will build bituminous roads using an indigenous technology, “Rejupave” developed by India’s oldest and premier road research organisation, CSIR-Central Road Research Institute (CSIR-CRRI).

What is Rejupave Technology?

• CSIR-Central Road Research Institute (CSIR-CRRI), India's oldest road research organization, developed the Rejupave Technology.
• It is beneficial for constructing high-altitude bituminous roads in low and sub-zero temperatures.
• The technology actively reduces production and rolling temperatures of bituminous mixes by 30 to 400 degrees Celsius, ensuring minimal heat loss during transit in snowy conditions and long haulage times.
• The bio-oil-based asphalt modifier of this technology significantly lowers the heating requirements of bituminous mixes and preserves mix temperature during transit.
• In cold climatic regions, the 'Rejupave' asphalt modifier enhances long-term durability and resistance to thermal cracking under low-temperature conditions.
• Additionally, it plays a crucial role in reducing greenhouse gas emissions in the eco-sensitive mountainous environment of Arunachal Pradesh.

About CSIR-Central Road Research Institute (CRRI):

• Established in 1952, CSIR-Central Road Research Institute (CRRI) stands as a premier national laboratory under the Council of Scientific and Industrial Research (CSIR).
• CRRI's major research and development programs encompass a range of projects, including the design, construction, and maintenance of roads and runways, traffic and transportation planning for large and medium cities, management of roads in diverse terrains, improvement of marginal materials, utilization of industrial waste in road construction, and landslide control.
• The institute extends its expertise by providing technical and consultancy services to various organizations both within India and internationally.
• CRRI actively contributes to capacity building in highway engineering, empowering human resources to undertake and execute road and runway projects.
