(OP)
We are dealing with a 230mm concrete pavement to be placed on top of an expansive clay, expansions are about 4% to 5%. We will place a 100mm cement treated granular base beneath the slab and we want to place a lime treated sub-base for swelling control. We would appreciate your advice on determining the thickness of this sub-base to control the swelling.

Also make sure you provide good positive drainage for any water that gets through the pavement so that it cannot penetrate to the expansive zone. If the water can't get there, it can't swell.
