Go to the experts - hopefully that's the place you will be buying your concrete from and explain what you want to do. There are more options than you might first be aware of besides just the thickness of the pour. Richer (stronger) mix - fiber in the mix - screen or rebar reinforcement etc. I have seen first hand what impact loads too a small area (like bumpers hitting the same spot repeatedly) and it ain't pretty - and redoing it is tough at that point (and expensive). The secret is spreading the stress out and that's why the multilayer plywood platform works so much better than the rubber alone. As stated before a well compacted base, an appropriate thickness or the correct type mix. with some type of reinforcement such as screen or rebar - then a suitable multilayer platform. Don't be penny wise and pound foolish.
