It should have been obvious all along.

Concrete is a much better material than asphalt. It lasts much, much longer than asphalt but it is hard to lay and can be a nightmare to repair. Asphalt can be scrapped up and laid down again quickly.

Now comes along the Tiger Stone:

This could change road building as we know it. The machine will allow for fast laying of concrete pavers at a speed equivalent to asphalt paving.  But have a better ease of repair than asphalt, with the wear of concrete.

Not to mention this is a first generation machine. They may be able to automate the process of actually putting the bricks in place. That would speed the process up even more….

It will be very interesting to see how this develops as a technology and as the social process of maintaining and building roads.
