From Spain, we now travel to India where Kerala State Roads and Bridges Corporation (RBDC) Managing Director Mohammed Hanish said whitetopping would be done on the existing roads as it would add more strength to the road.

Hanish made the comments after a 5.5km stretch on a local road was whitetopped.
