Have you any idea about the amount of paperwork necessary in Germany to pave a path that's going through a forest or, gods forbid, natural reserve, and that's before you need a study looking at the impact paving will have on the local population of red-footed sparkle toads. Ain't no bureaucrat doing that willingly.

Best you can hope for is a fresh gravel resurfacing, which TBH is plenty for a foot/bikepath. Foresters certainly won't complain their stuff can drive off-road, also, they're usually bureaucrats themselves and would be stuck with the paperwork.
