Bricks, Masonry, Asphalt and Concrete - Questions about concrete paver moldings

I am researching the idea of making my own concrete "driveway"pavers and have seen paver molding with 2.5 thickness. Will this thickness work? This is not for a patio but a driveway. I am a stay at home mom and want to make them as I can and for me this would be great because I don't have the strength to handle anything larger.
Will this 2.5 thickness work?
Any ideas on the type of "affordable"product to use?
What in your opinion would each paver cost. The area would be about a 25 x 25 space.
Also what type of molding would you suggest?

Thanks

No..it won't be strong enough. Most concrete driveways are closer to 4" thick and use a higher strength mix with a good solid compacted base under it.

Also, to use the brick type pavers that you see used for driveways at some houses, there needs to be something like 8-12" of compacted stone and sand base underneath. Those pavers are also much stronger and more weather resistant than the regular sidewalk or patio pavers.

Are there moldings out that with that thickness?

Are there any thicker paver molds 4 to 5 inches anywhere. I have searched and most of the companies I see only have 2.5 and state these will work for driveway pavers. Help?

The minimum strength for interlocking concrete pavers is 8000 or 8500 psi(I forget which - average or minimum), but some go up to 12,000 psi.

It is doubtful you can get the required strength by pouring in a mold, no matter how much cement you use. - Especially for a larger unit that will probably fail due to flexure/bending since your base may not have enough strength.

Look at the site for real paver suppliers that make units for driveways, streets, airport taxiways and heavy duty ship unloading terminals. Patio and sidewalk pavers will not cut it.
