Looking good to me. I think it will be a really nice area when finished.
I agree, there's nothing (including asphalt) that is invincible as a paving material - basically a plow can damage anything it passes over that isn't harder than the cutting surface of the blade (i.e. no paving material with which I'm familiar).
One of the advantages of these paver blocks is that they can be replaced individually if there is any damage rather than having to repave the street or pour a new section of concrete, for example.
Hopefully they don't take on a rusty appearance from the plow blade scraping its rust over them, like you tend to see on concrete sidewalks from the bobcats plowing them in the winter.
I do hope that sidewalk replacement is part of the scope of this project. Walking down Argyle on the weekend, it became obvious that most of the sidewalk there is in horrific condition - exemplified even more now that nice, new pavers are being installed.
