I have a large backyard (I'm an hour north of NYC). It is half asphalt and half soil (total 50' wide).
We tried removing some of the asphalt from the yard last year and the soil beneath it was just terrible. It needed to be removed completely and replaced. That's OK for small sections, but not for a chunk that's 25' x 25'.
So my question: we really just want to grow grass where the asphalt is. Is there any reason why I couldn't lay down some landscaping fabric over the asphalt and then put down 8-10" of soil and treat it like a raised bed? The yard is on a slight slope and needs to be regraded a bit anyway -- I thought that with the proper retaining walls this would be a good solution -- and at least keep all that asphalt out of the local landfill.
