I would not want to pour concrete on top of large roots just under the surface. Best to root plow and remove.
Have been watching about 200 acres of pine timber being logged, stumps and tops are then stacked and put thru a chipper. Chips hauled off. Lastly, they have started root plowing with a dozer while a tractor hauls off roots with a front end loader to the tops pile. A neighbor said another new housing subdivision is coming on this tract.
I had to stop and watch the dozer with root plowing long enough to realize he was doing a grid at a time with gps. I've spent some weeks on an open air D6 doing root plowing years ago and today's cab dozers are a huge improvement.
