Parking at home

Why concrete? I put down a layer of road fabric, then 4-6” of 4” minus gravel. Eventually I’ll put some 1” minus on top to smooth it out. It’s pretty rough but very solid, and I have driven 80k plus across it.

 

If money isn’t a problem then sure - go for it.

It’s nice of you to placate the neighbor, but @kylefitzy suggestion is what I did and it’s a heap cheaper than blacktop or concrete.

 

Figure out of it's legal to park commercial vehicles and equipment on residential property in that jurisdiction. If it's not legal, you can try your hardest to appease the neighbors, but they could always complain to code enforcement for any reason. Don't assume that just because other people around you are parking trucks on their property that it's legal, either.

 

If you don't care about beauty, just put some regular one and a half or two inch crusher run (basically just rock) on it. If you want to make it look "nice" put screenings on top of it. I am not sure how much that would cost, but I would think but don't know for sure that it would be a lot cheaper than what you are thinking about doing.

 

4” of concrete won’t even come close to supporting a semi. My previous driveway I poured at 12” and supported my bobtail with no problem.

 

Structure magazine says 8 inches will support a fully loaded concrete truck. 6 inches is enough for an empty. Axle weights should be similar I would think to a 5 axle 80,000 or an empty.

 

4" of 4,000 psi concrete is plenty to support a semi it won't crack it. I wouldn't waste money on concrete you'll definitely get sticker shock contracting it out. Scrape the grass off, spread and push in some 1-1/2" rock, then cover that with crusher run and do the same. That's all you need for a parking spot. The neighbor probably didn't do a good job on his rock is why he hates it.

 

4” concrete is a sidewalk.
