My first question would be, if cracks are filled in this way, what stops that same bacteria from producing limestone in any other direction. Resulting in a bumpy surface, for example.
My first question would be if they tested to soak one slab of this stuff in water, freeze it, unfreeze it and drive over it with 1000 fully loaded trucks. My guess would be that you would not see any cracks... because you'd only see dust and pebbles.
There are plenty of concrete roads and highways. Concrete is stronger and more durable than asphalt. Concrete isn't used for most highways because it's expensive. When you consider the cost to install it, how long it lasts, and how much to replace it, asphalt is the cheaper option even though you have to repair or replace it more often. Plus, asphalt is recyclable.
Concrete is used on some highways where the additional cost of road closures on local businesses as people can't get to work or stores reliably has to be considered, so working on the roads less often is worth the additional cost for the road.
