I think that coarse rock like the 3" base you mention should go down on top of the fabric and it should be followed by a layer of finer stuff like 3/4" minus. A good compacted and well drained base is key to making any road or foundation. The fabric keeps the rock from disappearing into mud when things are wet. I am not sure that top soil is the best soil for base material.
