Levelling compound wont work over tile. All tile and adhesive must
come off first, and I bet it's asphalt time with tar adhesive. You
wont get all that tar off. If you got enough headroom, you might be
best pouring another slab right over the old one. Slabs are normally
4", but I think 3" would work over the old one. (I'd still remove the
tile). Otherwise break out the whole floor and start over.
