Driveway thru wet area
Driveway thru wet area
(OP)
I took out all the topsoil and filled the drive with about 3' of sand, then top it with 8" of road gravel. It seemed hard as a rock, but then I had about 15 gravel trucks go in and out and a section of the drive turned into jello. Is there anything I can do to fix this?

As discussed in the elizasue1's post it is difficult to make a recommendation without seening the site and determining the nature of the problem.
You could bring in a geotechincal engineer to take a look and make a recommendation. Our company has an office in Toledo and does work in N.W. Ohio and S.W. Michigan. We'd be happy to help if your located near us, otherwise, a good contractor or structural engineer can recommend a geotech firm thats closer to you.

One question, did the soft zone seem to "tighten" back up after the trucks were done with their jobs?

I have had a similar problems in the old farm areas of Delaware. Delaware is by nature sandy. The problem first arose when a stabilized construction entrance seemed to do the jello role. Our soils engineer could not confirm a high water table nor was the soil bad. Further investigation shawed a hard pan layer which would not let the water infiltrate. The solution for the entrance was to lay Geo-Grid and stone. Worked great. With your high water table this should work fine for you also. The rest of our Site we just broke through the 3" thick hard pan @3' depth and foundations and infiltration areas worked fine.
