Road pothole machine

Currently to fix the road holes we milling old asphalt than put a new one. Here is my cutting expense solution.
Instead of ripping off,  my recipe is just clean, scan in 3d , heat very hot to melt some bottom layer, than put some tar, fine sand than new asphalt (just enough for the pot).

Since 3d image provide the shape of the hole the patching would be the same as in 3d printering (or even easier 2d) - just put calculated amount.
Low speed compactor at the end most probably just make initial compaction and road roller will finish behind.
Due to hole only filament the constraint asphalt supply is not essential.
The cutting drum only to even the road bumps.


Small research... some starting thinking in the same way
