alt Hacker News> Mozee went into detail comparing slow concrete curb accessibility work to the faster asphalt street work. Per Mozee, “there’s approximately 14 ramps in a mile.” So for “one crew to build out those 14 ramps will take approximately three months.” In contrast, he said, “a paving crew on a good day … could pave that same mile in a weekend or one week, at most.”
Why don't they asphalt curb to curb for a mile and then come back and do the ramps one at a time?

As someone who did a stint in this kind of construction: not possible, you'd still need to re-pave about 30-50cm worth of road, because curbstones are (usually) suspended in a bunch of concrete to avoid them getting dislocated by cars hitting or driving over them. The result will be a faultline from which you will get potholes in freeze cycles.
The proper way is to do everything at once, leaving one slab of contiguous asphalt without faultlines.
Because you need to build a form for concrete, and to build the form after paving means you'd have to cut then patch that new asphalt, which will just end up forming potholes.
