Iowa | Fabric is the key. I bet you would have had similar results with smaller limestone. Anyway, it worked well and that's all that matters.
To OP, If spot is "high and dry, I'd just "fabric" it and add limestone w fines. After that packs, if dust is a problem, put some "CLEANED" over it.
We do driveways all the time on top of virgin soil if site is well-drained. Fabric is the key. Unless strictly residential, we use the heavier "truck" grade (vs. the "car" grade).
Fabric provides extremely good value. No annual $$ for more and more and more and more rock, no "bottom falling out" each spring for the first several years, etc. Limited or no washboarding, no potholes.
Good call on the fabric! | |
