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

1.56K viewsOther

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?

Sometime they rip up the road and then it takes a time to work on the lines, hydrovac, maybe replace some or repair some while the road is ripped up, then a few weeks to rip up and pour the concrete for the sidewalks, which my not been noticed if you are just driving down the road but it is slowly being completed. Then another day or more to sweep the now dirty road before new asphalt can be laid down. Then depending on the length of the stretch a several days to pave, and they may do one lane at a time so the asphalt has time to set a bit before it’s driven on. An inspector might come from the municipality which could be delayed. Suddenly several weeks went by, but it’s been being worked on the entire time. It’s just unnoticed by the general public.
