2. The "bedrock" was in fact softened limestone, or reconstituted limestone, in a putty type consistency and acted as if mortar. "
If its not too annoying, I'd like to introduce a third option.
3. There was an unknown advanced material science that existed at some point in the past that afforded them the ability to soften rock. And it appears from the visual evidence of all megalithic work that has the most flowing, modeled and pillowed appearance, that it was most effective with igneous rock. So with that ability, the Basalt rocks were placed over the uneven surface below and this tech was applied to it to melt it over the subsurface and flatten the top surface.
- If you are hoping to have an interlocked paved stone surface that will resist separation from tremor, its best to have a very convoluted and uneven subsurface to aid in a lateral movement resistance.
- Achieving a perfectly leveled surface with multiple stones over uneven subsurface, it makes sense the ideal tech to possess to achieve that, would be the tech that would allow them to level the surface while the piece is in situ, using the literal reference of the piece immediately next to it.
- With each basalt stone pad having a perfect 100% contact surface on its bottom, there is no need to have large basalt pieces as huge single piece plates, and bringing smaller stones in to pave this area one at a time is efficient for ease of transport.
- If in the past damaged area's were reassembled, as evidenced by the images where basalt pave stones were askew and strewn about, its completely within reason to tackle the job of restoration by visually matching the contours of the bottoms of the stones to the contours of the rock subsurface. It would actually be a relatively easy, albeit slow, but fun project. And considering the alternative to that is either cutting and flattening stone, or mixing and pouring tones of concrete, and allowing it to set just enough so you could place the basalt to achieve a perfect surface level with its adjacent matching paver, without sinking too far, or sitting too high, its an absolute best approach to restoration of this surface, especially since each piece is maneuverable by human hands and a few leverage tools.
I needed to read through a few of your posts about this issue before I completely understood what you were saying. At first I thought someone knew for a fact there was concrete used for all of it, but on further reading, I'm understanding you are just supposing that based on your different speculations about this work.
I've seen this basalt stone area many times before, but I never actually knew it was set over top of a completely uneven subsurface. This is another great example that points to stone melting tech to me.
