Which one of the following statements about ‘REJUPAVE’ is correct?
- (a)It's a joint venture between Food and Agriculture Organisation (FAO) and Government of India to promote organic farming
- (b)It's the name given to the lightest surveillance aircraft developed by DRDO
- (c)It's a centrally sponsored flagship Programme of the Ministry of Women and Child Development, Government of India
- (d)It's an indigenously developed road construction technology at high altitudes
Correct — D, it is an indigenously developed road-construction technology for high altitudes. REJUPAVE is a bio-oil-based asphalt modifier developed by CSIR-Central Road Research Institute (CSIR-CRRI). It lowers the heating and laying temperature of bituminous mixes so that durable roads can be built in sub-zero, high-altitude regions. The Border Roads Organisation (BRO) has used it on high-altitude roads in Arunachal Pradesh (the Sela Tunnel approaches) and in the Ladakh/Kargil sector.
- (a)It's a joint venture between Food and Agriculture Organisation (FAO) and Government of India to promote organic farming — REJUPAVE has nothing to do with the FAO or organic farming; it is a road-building material.
- (b)It's the name given to the lightest surveillance aircraft developed by DRDO — REJUPAVE is not an aircraft; it is a bituminous-mix technology from CSIR-CRRI, not a DRDO aircraft.
- (c)It's a centrally sponsored flagship Programme of the Ministry of Women and Child Development, Government of India — REJUPAVE is not a welfare scheme; it is an engineering technology for road construction.
REJUPAVE is a warm-mix/rejuvenator asphalt technology from CSIR-CRRI that keeps bitumen workable at lower temperatures. This matters at high altitudes, where extreme cold otherwise makes conventional hot-mix paving fail, so it enables strategic border-road construction.
The four options span farming, a defence aircraft, a welfare scheme and a road technology. The name (the 'PAVE' element) and its CSIR-CRRI origin point to paving — option (d). It is valued for building roads in freezing, high-altitude terrain.
- REJUPAVE is a bio-oil-based asphalt modifier developed by CSIR-CRRI.
- It lowers the production and laying temperature of bituminous mixes by tens of degrees.
- It is used for road building in sub-zero, high-altitude regions.
- The Border Roads Organisation has deployed it on Arunachal Pradesh (Sela) and Ladakh/Kargil roads.

- Being misled by the 'DRDO aircraft' or welfare-scheme options; REJUPAVE is a CSIR-CRRI road technology.
