I consider the massive ramps that orthodoxy envisages to be problematic for a number of reasons which have all been elaborated upon many times before on GHMB so there's little need for me to do so again here. I do, however, think there would have been slightly inclined 'transportation roads' to get the blocks from the quarries to the base of the pyramid but these could hardly be described as 'ramps' in the conventional sense.
As you may know, I have previously proposed the AEs could have utilised the power of thermodynamics through the application of some form of 'envelope' or balloon filled with hot air to raise heavy stones. There is some evidence around Giza which could support such a hypothesis: The Flying Stones of Ancient Egypt.
