New walkway using pavers

I'm removing my old brick walkway this year. And i'm puttingin new pavers. I picked everthing out and have the design I want. I want to see what I really need for a base. I'm in NY between nyc and Albany. I was at my big box store and there is the stage 1 base bag that says 3" thick and tells me to add 20% for compaction. So My plan is to do a 4" thick base and should I cal. for 20% compaction lose? Plus a 2" thick of sand, then the pavers. Should I cal. a 20% compaction for sand too?

 

What's in the stage 1 base? Is it crushed recycle? You probably only need between 1 & 2" of sand & I would mix the sand with Portland cement, 3 sand to 1 Portland.

 

What kind of paver? - Interlocking concrete (the most common), clay brick are larger "(steeping stones - over 10" in any one dimension)?

For interlocking concrete pavers, have a uniform 1" thick sand setting bed (screeded since sand does really not compact) and make your compacted base determine the slopes, if any. Set the pavers tight, toss or spread fine sand on top and then vibrate the surface with a vibratory compactor to works the sand into the joins to create a smooth surface and create a stable paver/base surface.

it's name is Paver Sand Type Paver base, its go sand and small white stones in it.

I'm using 6x6, and 6x9 1" thick concrete pavers. They do not interlocking, but I can put them side by side.

Well what I have now are old bricks that move all over the place with the cold and warm weather, I duged down on a couple to see what was there and there is only 1" of sand then just normal soil.

 

You have a relatively unstable base and pavers will be susceptible settlement and you can expect some ups and downs in a walkway. You can but them up to minimize differences in the individual pavers. They are only 1" thick and there is no way to really get them as tight as a real paver installation that obtains the "interlock" by the fine sand that is vibrated in the tight space that is about 2 3/8" or 3 1/8" that is the depth of the real paver.

You have a poor base that will always have some settlement unless you create a strong , thicker compacted base.

It all depends on what you are willing to accept since you are laying them on "normal" soil.
