When cities repave roads, why do they leave the street ripped up for a couple weeks before repaving?

Question

I was told once it’s because cities project the job to take say 5 weeks, so they rip it up the first week, leave it for 3 weeks, then repave the last week. And they do this so everyone gets a paycheck for the full 5 weeks. Surely there has to be a different reason?

Since you’re ripping out the pavement you may as well call utility companies to inspect their equipment and do any necessary maintenance, since it’s usually a bunch of companies this may take weeks.

Not saying that’s true everywhere, but in some cities it is.
