The main mode of transportation is by road or highways.
In the process of road development, the alignment of road may have to be fixed through the soils which may not bear the traffic loads .
There are various techniques of ground improvement.

METHODS FOR GROUND IMPROVEMENT
Soil stabilization
Vertical drains
Stabilization trenches
Capillary cut-off
Soil nailing
Stone columns
