Thanks, Tom.
What I'm looking for is a granular, somewhat loose appearance. I couldn't tell from that link if Typar is a solid surface. Are you suggesting it as an underlayment for the stuff Dale mentioned? The traditional concrete or asphalt would not do, but a tightly-packed (dustless) stone/sand mix, like Dale suggested, seems to be the answer.
Like I said, I want two tracks with grass between, winding its way back to the new garage. I want it to look like a trail through the trees rather than a driveway.
Bob, Typar is a fabric underlayment that acts as the base for any gravel or other finish material.
It is like a blanket and it works on the principle of evenly spreading the load. Instead of depressing into a rut like would happen with a gravel, dirt, or thin asphalt road, the the weight of the road materials are evenly disbursed so you do not get the ruts. The other feature is that the road becomes more flexible to freeze / thaw cycles.
Asphalt alone will rut and break up from both your weather cycles and shear vehicle weight. Concrete needs to be a minimum of 4” thick and have rebar imbedded within to keep it from breaking. As you said, neither of these give look you want anyway.
Another method I’ve used to keep the “green” look is to use create a roadbed of concrete blocks then fill the cores with dirt. You can seed the cores, get a green look, but still have the strength of the concrete block as the road surface. Again, do this over the Typar fabric, followed by a layer of sand or P-gravel. The dirt you excavate for the block could be used to backfill the cores.
The home I grew up in had a regular driveway in front but Dad constructed a drive that wrapped around the house and went back to the barn. He used a product called Pit-Run Gravel which amounted to a mixture of various size gravel rock and clay.
We never had a problem with it except for some rutting that would have been eliminated had Typar existed at the time.
The only problem with it for your use is that it looks like a gravel road so don't expect the grass effect.
It may cost more, but for the look you want, I’d check out the block / Typar combination.
Hope this gives you something to ponder.
