    Driveway

    The 2 acres I bought has an existing concrete driveway that I want to use, but it seems it’s level with the ground , or in some places lower. Can see in places where it holds water. I don’t want to demo the driveway and repour.

    Has anyone ever put a gravel / limestone drive on top of existing concrete?

    If you leave the concrete and put limestone on top, the water will still sit on the concrete. The limestone will still allow water to flow to the low spot and the concrete wont allow the water to filter down into the ground

    Also limestone on top of soil typically gets packed down and it "locks" itself in place. If it's on top of the concrete it may not lock in. With it sitting on rigid pavement the limestone may move around when you stop your truck. The concrete surface will allow the rocks to slide, depending on how thick you lay it and the size of your limestone.

        I was going to put a base layer down first before the limestone of a dirt and crushed concrete mix

            Use the concrete as a base and asphalt 2" thick on top of it. Loose rock on it will end up in the yard

              if you go with gravel use a flex base material txdot item 247. i would go min 6 inches above the concrete. you have sub grade failures going on where the alligator cracking is occurring. my two cents but don't chase bad with money. do it right once and be done

                From my experience if you put flex base on top likely it was wash off/ move since it won’t be able to compact into something to hold it in place.

                If you place asphalt over it there is a good chance those cracks will eventually come into the asphalt.

                Best bet would be to remove the concrete and place a good flex base or road millings down to replace. Makes sure to compact it the best you can.

                  Hard to say for sure from the pictures. But I think that you'll still have the same problem with holding water. I'm not sure what your plans are for the property, but it looks like you are in the middle of a lot of improvements. Thinking long term, it may be best to remove the driveway and grade the property to drain properly. Then you can lay down a driveway of your choice.

                  The cracks in the concrete will quickly reflect into the asphalt. Asphalt won't take long to break down after that.

                    Another observation. It looks like you have some mature trees around that spot that's holding water. My bet is that over time those trees' roots have gotten used to pulling moisture from that area. Between the shade, concrete cover, and tree roots the ground in that soil is most likely very wet and not suitable for a strong driveway.

                    That's why I say that getting it to drain properly would be an important step prior to investing in any improvement for your driveway.

                      Short answer is you could but it wouldn't hold up long term. I would just spread the crushed concrete and millings between the trees and the metal building and use that for a driveway.

                        The metal building and everything to the left isn’t mine. My property line goes to the left of the driveway prolly 20’

                          I'll 2nd what the other person said, trees that close to a drive is asking for trouble ... broken concrete, broken pavement, possible root surfacing, etc. etc.

                          Do you have a different route you could follow?
