Bricks, Masonry, Asphalt and Concrete - new driveway - rain

We had a driveway addition poured Friday morning. (3 days ago) When I got home from work they were finished. The forecast called for rain so they covered the driveway in plastic. When the removed the plastic the next day ,the driveway had slight water on parts where it had made it under the plastic. Saturday was warm and mostly rain free except for a light sprinkle through parts the day. It rained some Sunday off and on and poured really, really bad today. (it figures, we have had a 2 month drought until I did this :( )

How long before the concrete (3000 mix with fiber) can take on water? He told us since he was able to step on it when we got on home Friday, it would be fine, especially since they were covering it until the next morning.

I know we are not supposed to drive on it for a while

What do you think, am I OK?

here is a picture on Saturday about 4:00 pm

It is supposed to rain all day tomorrow then sunny for a week.

As long as the surface wasn't marred by it, the rain is actually the best thing for the concrete. It will keep it moist and let it cure slower (a good thing). The worst thing would be if the plastic left marks in the concrete. Concrete can set up underwater, so exterior sources of water are NOT an enemy.
