I've seen projects to pave only a few miles take years. Not even roads that are that busy, even.

That doesn't sound right, assuming a lane width of 3.5m, they can only resurface roughly 29 square meters an hours?

With all that equipment and manpower.

you need to scrape all the way to the base and then fill back in when repaving. and you also can't lay asphalt in rain.
