Q.Tulip tree – diameter and root question
I recently purchased a tulip tree. Full sun and (relatively) good soil. Can you tell me – what is the diameter of main trunk for a mature tree? Second question – Would the roots lift a 24″ stone walkway located 2′ away from best planting site?
Assuming you are referring to tulip tree, sometimes called tulip poplar (Liriodendron tulipifera) and not tulip magnolia, or African tulip tree:

--they are a very large growing tree, with a mature trunk diameter of 2 feet in 20 years possible, and 3 feet or more in 40 years. And yes, the roots, in time, would almost certainly lift a walkway even 4 to 6 feet away or more. They are beautiful, but need plenty of space.
