Construction of roads over moraines / Permafrost/ glaciated areas.
(a) BRO continues to construct roads in super high-altitude areas along India’s Northern borders, where the ground is underlain with permafrost/ moraines/ glaciers.
(b) The alarming pace of climate change in recent years has triggered repeated cycles of freezing and thawing of permafrost, because of which the natural sub-grade has become unstable causing damage to existing roads and preventing construction of new roads in such like areas.
(c) The challenge is to either find innovative means to stabilise the sub-grade or develop technology for construction of roads over permafrost/ moraines/ glaciers
