I don't know very much about this process, but grading is clearly crucial. This image is one of multiple passes that several different machines made up the street as each new layer was put down. There is also a guy on foot who is constantly measuring.
What you don't realize is that a road isn't flat, it actually has a very gentle slope, rising up to the middle. This is so water can run off into the gutters. I really have no idea how they get that slope, but it sure was consistent. Most impressive.
Look at that beautiful smooth road, it's dark-grey matte surface welcoming the late summer sun.
See how tightly it fits up against the new sidewalk. Really satisfying to look at for some reason.
Let me tell you, this thing is really nice to ride your bike on. It's practically a velodome. Same for cars I imagine because sadly, they are back. And what's worse this new road really encourages speed so they come whipping up the street faster than ever. I really should have tried to get a speed bump in place when I had the chance. Oh well, I guess it's back to caltrops. And yelling.
