This is quite an engineering feat!
Too bad we don't have this in the US.
Tiger-Stone is a Dutch paver laying machine that can produce brick roads. Paving bricks are dropped by front-end-loader onto the angled trough. Men help to spread them in the trough as they drop into the forming jig.
As the electrically operated crawler moves forward along a pre laid sand base layer, All the stones are packed, gravity held together & descend the sloping ramp on to the road.
