[QUOTE="Kurtr, post: 173399, member: 194"] a plate packer wont do it if we are talking about doing it right a jumping jack will be needed and the right amount of water so as it does not go over the curve but then a proctor would be the only way to know it then getting density shot would be needed as any thing under 98% would not be acceptable........ that is utterly ridiculous your building a patio and not a sky scraper me personally i put fill gravel under my new house my garage floor and then base course ( in ND that is class 5) under my drive way because if water gets under there some way i dont want it to sit i want it to drain. With the rebar in it the biggest factor is going to be your concrete guy and sawing it at the right time and making sure he does not slop it up and you get a bunch of shrinkage. Plate packers make it look nice but do little in the way of packing any thing but the top two inches and i have dont a whole bunch of density testing that has proven that as fact. Is the crushed concrete blended with gravel to make it pack better or is just straight recycle? Who owns the pit by your house i am sure they have production reports that can be found. [/QUOTE]
