I am trying to break up an access road on a job site that is heavily compacted. Most of the job is complete and seeding has been done every where but the access road. The job is coming to end and we would like to clean up and move on. The access road has had everything run across it for the last 6 months. A stready diet of loaded tri axle dumps were part of the mix. The LCO I sub for wanted me to put my aerator on it. I have a Ryan tow behind. It does a greeat job but it's for existing turf areas not a construction site. I told him the aerator isn't going to break it up. I suggested we use a 3 pt tiller instead. I tried today and it didn't do much good. It was slow and after the first 4-5" you still have major compaction. Not to mention the amount of rock and crap we pulled up from the fill that was hauled in. The job is a public park with baseball filed being the focus. This access road is parallel to one of the fields. It needs to be done right as it will be in full view. I was thinking either a 3pt subsoiler or bottom plow attachment. I've never tried these. Does any one have experience with these attachments or this type of situation. I need to go as deep as I reasonably can and break this road up.
