Which indigenous road construction technology has been recently successfully utilized in Arunachal Pradesh for constructing high altitude bituminous roads under challenging temperature conditions?

Arunachal Pradesh has successfully implemented the indigenous road construction technology “REJUPAVE,” developed by CSIR-Central Road Research Institute (CSIR-CRRI), Ministry of Science and Technology. This technology has been specifically designed to construct high altitude bituminous roads in low and sub-zero temperature conditions, a scenario prevalent in the region, especially near the Indo-China border. The use of REJUPAVE is particularly significant for the Border Roads Organization (BRO) in their project VARTAK, as it addresses the challenges of building and maintaining durable roads in harsh and cold environments. The technology has proved its efficacy in constructing bituminous road sections at the World’s Highest Sela Road Tunnel and the LGG-Damteng-Yangste (LDY Road) road section, showcasing India’s innovative capabilities in road construction under extreme conditions.
