Context: 

Recently, the Border Roads Organisation (BRO) has utilized the ‘Rejupave technology to build bituminous road sections at the world’s highest Sela road tunnel and LGG-Damteng-Yangste (LDY Road) road section near the China border in Arunachal Pradesh.

About Rejupave Technology

• Developed by: CSIR-Central Road Research Institute (CSIR-CRRI).
• Use of a bio-oil-based product: Rejupave asphalt modifier is a bio-oil-based product that lowers the heating requirement of bituminous mixes besides preserving the bituminous mix’s temperature during transit.
  • Bituminous Road: It is also known as the asphalt road, is a type of road construction that involves the use of bitumen as a binding agent to hold together a mixture of aggregates. 

• Significance of Rejupave Technology: 

• • High-Altitude Bituminous Roads: It is beneficial in constructing high-altitude bituminous roads at low and subzero temperature conditions.
  • Temperature Reduction in Bituminous Mixes: It brings down the temperature of bituminous mixes by 30 to 40 degrees Celsius with negligible heat loss in the bituminous mix during transit.

About CSIR-Central Road Research Institute (CRRI):

• Establishment: It is a premier national laboratory established in 1952.
  • It is a constituent of the Council of Scientific and Industrial Research (CSIR).
• Mandate: It is the premier national research organization for highway traffic, transport planning, and other allied aspects.
