Portland Cement Association's FAQ Available Online Here's a Glimpse:
Q: My concrete driveway was built last year. This spring I noticed that there are areas where the broom texture has worn away and in one area the surface is rough and I can see some of the stones that I believe to be fairly deep in the concrete. What causes this and should I be concerned about the long-term durability of the driveway?

A: What you are describing may be scaling, which is a general loss of mortar from the concrete surface. This mechanism is typically caused by one of the following physical processes:

concrete that is exposed to multiple freezing and thawing cycles when the concrete is saturated with water
concrete that is exposed to deicing chemicals
In either case the concrete surface is disrupted by tensile forces that develop as the result of water near the surface which expands as it freezes. More.
