It would not be the first time that a section of road pavement has had to be taken up and redone at the contractors expense due to a mix problem at the ready mix plant.

It might have been rained on. In which case they cover it in poly, but if the plastic rests on the concrete it sometimes impacts the brush marks, and depending on the inspector, it may not get accepted.
I would think (but I don't know) that a sidewalk would be held to a higher standard for texture. If 5m of a road lane have slightly more slippery texture you probably wouldn't notice while driving on it. But a sidewalk with a smooth texture can be very slippery when wet.
