Demonstration of a road-laying machine. Workers receive the stones with a conveyor belt, lay them on a sloping surface against each other, after which the machine lays it on the ground and stamps it. With this machine a road of 250m by 3m can be laid in one day.
Human-made No record of this work says a model made it. What this means.
