Question map
Which one of the following statements about 'REJUPAVE' is correct ?
Explanation
REJUPAVE is an indigenous road construction technology developed by the CSIR-Central Road Research Institute (CSIR-CRRI) [2]. It is specifically designed to facilitate the construction of high-altitude bituminous roads in low and sub-zero temperature conditions [3]. The technology utilizes a bio-oil-based asphalt modifier derived from biomass and renewable resources, which significantly lowers the heating requirements for bituminous mixes and prevents heat loss during transit [2]. This innovation is crucial for maintaining road durability and resistance to thermal cracking in extreme climates. The Border Roads Organisation (BRO) has successfully deployed REJUPAVE for strategic projects, including the Sela Road Tunnel in Arunachal Pradesh at 18,000 feet and the Drass-Umbala-Sankoo Road in Ladakh [2]. By reducing production temperatures, it also minimizes greenhouse gas emissions in eco-sensitive Himalayan regions [2].
