+1 for @JOG 's advice. The concrete would be an excellent base for a natural stone or concrete slab product over the top. In fact for vehicle loading, especially a driveway which is prone to channelisation where the wheels run, concrete would be the preferred foundation type unless you get into really chunky expensive slabs and thick sub base layers.
Only thing I would be cautious of with the resin bound solution would be to specify a non-permeable product if you choose to direct lay it over the concrete. A lot of resin types are permeable which could lead to water permeating through and sitting on top of the concrete/within the resin product. This would be bad news in the winter if subject to freeze thaw action and could result in premature failure of the surface. However, I would check with the resin manufacturer if their product is classed as a 'non frost susceptible material' in which case shouldn't be as much of an issue. Something to consider anyhow!
