Mr Clownshoe.
Ironhippy has basically hit the nail on the head. Note that my method works in this scenario
- Trail and surrounding area already has lots of organic content
- Trail cannot be too steep (it does work on steep trails but tends to get washed away thus requires lots more work)
- Trail cannot be too busy. 20 + riders a day is about right for carrying capacity of a loamer before the loam gets worn away. If a trail gets snowed under more generally it reloams more. If a trail is north facing it reloams more (SW winds blow tree needles and leafy debris onto N trails).
Generally speaking for loamers, loam-wear happens because water flows down the trail or people brake. I try to address water damage with the standard grade reversal. Excessive braking i try to address by sending a steeper section onto a small uphill that bleeds off speed (eg what your crew did with Midgard)
Where there's trail wear and it gets excessive I do what ironhippy suggests. I repair using mineral/gold soil and rock. Then I layer the red-rot/loam on top.
The work involved is usually in finding the gold soil, the rock and the loam. First prep the wear location. Find a location close by ideally with a mix of rock, loam and gold dirt. I'll excavate the moss, the loam, ferns, salal etc and put it aside somewhere close at hand. Dig down to gold mineral soil and if there are rocks separate that out too and put somewhere close at hand.
Then do the standard stuff to repair the worn location but layer the big rocks, then small rocks, then soil then organic loam on top. The slow part is renaturalizing the work area after Im done but my personal goal is to keep the trailbed narrow and green so I'll use the moss, salal and ferns for that purpose after.
For mild wear sections where roots are exposed I'll just find mines of organic red rot or better yet, old rotten logs and scatter that onto the trail then break up the material so it mulches into loam over time (a few months of riding does the trick). I find the loam then makes the roots really slippery so they come into play when it rains so it serves the purpose of making the trail ride like ass when things get wet. This keeps people honest so I don't have to lecture riders to stay off loamers in the wet. And if someone has old school tech skills and can ride it in the wet - well more power to them
Hope that helps
