Paving slabs are just a finish to whatever you put underneath them. Put a good enough base under any material, and it will hold the weight you require.
I have laid sandstone driveways (sandstone is on average 20mm thick) this is still (somehow) intact to this day, 6 years on with daily traffic over it.
You can happily use pre cast concrete slabs for what you are after Tom. Use a good base (150mm of base ie scalpings or crushed hardcore, 20mm of lean mix, then your wearing course) and you will have no problems.
