Years ago a local salvage store had 3/4" flooring sheets on sale and I bought a bunch - but OMG they are so heavy I don't know how I got them moved around. When I built my road course 2+ years ago I went with 1/2 MDF, still heavy stuff but much more manageable.
The best part of my 6' x 14' are the elevation changes. The start straight and pits are at table top level, but the rest of the track was cut out from the sheets and rises up to form multiple levels. The 1/2" MDF from Home Depot worked out great for an elevated back straight and a banked corkscrew turn that is sooo fun to drive.
My only suggestion would be to prime/seal all sides of the sheets before starting work on the track. I intended to do this but only sealed the top surface before impatience took over and I started routing and then couldn't wait to get it taped and wired. No problems so far, but one more day of prep time would have been good.
