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?

Man…. unrelated, i know some countries like Japan and (I think) Netherlands, pays for roadwork completed only so there’s a huge incentive to not delay on fixing things.
