I have read your ideas about roadways for battle arenas, and the need to use them in order to reduce grass damage to the wheel and track mechanisms on the tanks....so here is an idea.....
I often make toyboxes in the shape of Thomas the Tank Engine.....
To make the boiler section I buy plywood or hardboard that has cuts across the full width of the rear side of the sheet, these cuts penetrate half wway through the thickness of the sheet.
So I have a sheet that is smooth on one side, but looks like corrugated cardboard on the reverse side. This makes the board very flexible.
If you cut the sheet to make your road way shapes, coat the corrugated side with a good varnish, and the smoot side is coated with stone paint, you have a good road that will follow ground contours. The varnish will prevent moisture ingress distorting the sheet permanently.
The sections can be held/joined with velcro strips. I make small road sections like this for my grandchildren to run their cars on in my garden.
Worth a thought eh???
