I’m curious about the plaster material they used for paving—how durable it was, how they maintained it, and just plain what it looked like.

Same here. The Inca stucco was typically painted, has larged been washed off by the rain, leaving the rough stone walls, and the Mayans lived in at least as much rain and a lot longer ago.
