Here's a little trick I picked up quite by accident for making pavement.
Because I have a base of homasote, the texture has to be covered. I use spackle because it's lightweight and easy to work with.
I lay it on with a spreader and use a fairly light coat. Initially, the first pass or so tends to leave gaps with irregular edges. Here's the trick: instead of filling those gaps I leave them. Once painted they make very convincing potholes. Sprinkle a little fine ballast to simulate gravel.
Also, for modelling industrial areas where the paved areas often meet up with bare ground, don't be too careful with the edges. Draw yourself a guideline but don't use anything else to define the edges - just use the spreader. The variations give it a quite realistic appearance.
The first pic shows just how carelessly I do the spackle.
The second one shows how it turns out. (Note there's a curb for part of the driveway but not at the right corner)
