Concrete squares for driveway/walkway

I'd like to build a path alongside my driveway out of concrete squares/rectangles that are somewhat randomly placed. Most of the time it would be acting as a walkway, but since we have a single driveway and multiple cars, there are times when I would like to be able to park half of the car on the walkway. I hope that makes sense.

I am thinking of digging down about 6 inches for each square/rectangle and filling it in with 2" of sand, tamping it down, and then pouring 4 inches of concrete over that. Then I will let grass grow in between the concrete squares/rectangles.

I will then continue this around the side of the house as a pathway to the backyard.

Does this sound like it would be sturdy enough to park on? I live in Amarillo and occasionally we do get a freeze, but not often and not usually very severe. Would I have problems with these moving or heaving?

I am attaching pictures of the layout to give an idea of what I am thinking. I put my sandles in one picture to give you an idea of the size squares/rectangles I am thinking of.

Thanks for any help.

 

If it was mine I would just dig out that whole area 8" deep, compact it, add 6" of crush and run and compact it in layers. Finsh with 2" of sand, then set the pavers level.
Concrete set like your suggesting is not going to do anything for you. and is one of the pavers did get out of level you would have no way to adjust it.

 

Thanks Joecaptions1 for the reply.

So are you saying set the pavers and then fill in between with dirt and grass?

 

I think that's what he's suggesting. Be prepared for some differential settlement of your pavers, with those getting more tire loading having a tendency to get pushed downward (and possibly a bit horizontally as well), compared to the ones that only see foot traffic.
